Stacks of compact disc cases

Optical disc packaging is the packaging that accompanies CDs, DVDs, and other formats of optical discs. Most packaging is rigid or semi-rigid and designed to protect the media from scratches and other types of exposure damage.

(2) CD-Single
(3) Slimcase
A jewel CD case.

A jewel CD case is a compact disc case that has been used since the compact disc was first released in 1982. It is a three-piece plastic case, measuring 142 by 125 by 10 millimetres (5.59 in × 4.92 in × 0.39 in), a volume of 177.5 cubic centimetres (10.83 cu in), which usually contains a compact disc along with the liner notes and a back card. Two opposing transparent halves are hinged together to form the casing, the back half holding a media tray that grips the disc by its hole. All three parts are made of injection-moulded polystyrene.[1]

The front lid contains two, four, or six tabs to keep any liner notes in place. The liner notes typically will be a 120 by 120 millimetres (4.7 in × 4.7 in) booklet, or a single 242 by 120 millimetres (9.5 in × 4.7 in) leaf folded in half. In addition, there is usually a back card, 150 by 118 millimetres (5.9 in × 4.6 in), underneath the media tray and visible through the clear back, often listing the track names, studio, copyright data and other information. The back card is folded into a flattened "U" shape, with the sides being visible along the ends (often referred to as the spine) of the case. The ends usually have the name of the release and the artist, and often label or catalogue information printed on them, and are designed to be visible when the case is stored vertically, 'book-style', on shelves.[citation needed]

The back media tray snaps into the back cover, and is responsible for securing the disk. The center is a circular hub of teeth which grip the disc by its hole. This effectively suspends the disk in the middle of the container, preventing the recording surface from being scratched.[1] The media tray was originally constructed of a flexible black polystyrene, but many newer trays use a more fragile transparent polystyrene. This allows the reverse of the back card, which is usually used for additional artwork, to be visible. This format did not become common until the mid-1990s.[citation needed]

The jewel case is the standard case used by the majority of manufacturers and it is the most common type of case found in record and movie stores. Jewel cases are occasionally used for DVDs, but generally not for those that contain major film releases. Blank Blu-ray Disc media is also most commonly sold in standard-width jewel cases.[citation needed]

Origin

According to Philips, the name "jewel case" reflects either the generally high quality of the case design compared to initial attempts, or its appearance. According to one publication,[1] initial attempts at packaging CDs were unsatisfactory. When the new design, by Peter Doodson, was found to be "virtually perfect" it was dubbed the "jewel case".[1] Another publication[2] quotes Doodson describing that he "specified polished ribs as they pick up the light and shine" and states that the resulting appearance led to the name.[citation needed]

Strengths

Endurance: The CD jewel case has a tight and firm grip of the CD because of the tray's "teeth" or "lock". Because of this, even if the CD jewel case is turned upside-down, left, or right, the CD is held in place. Flimsier cases may cause the CD to become loose, or even fall out. Also, since the jewel case is made of plastic, it is sturdier compared to cardboard, paper, or foams. When pressure is applied to the CD jewel case, the case will break first before the CD. If the case is made of thin cardboard, there is a greater chance that the CD would break or get damaged because the weight is directed onto it.[citation needed]

Storage: The type of material of the CD jewel case allows storage of CDs for decades without ruining the CDs. The same is not as true with other cases, since paper can stick to the CDs due to air, humidity, and other factors. The CD jewel case may also be preferred because it offers orderliness on a shelf. Since the CD jewel case has existed for decades, there are many CD shelves, racks, and other products in the market that are made for CD jewel cases.[citation needed]

Room for accessories: The CD jewel case is designed to carry a booklet, as well as to have panel inserts. These may be used to display album artwork, lyrics, photos, thank-yous, messages, biography, etc.[citation needed]

Cost-effectiveness: Because the CD jewel case is the standard, most-commonly used CD case, it is much cheaper. The price of the CD jewel case usually ranges from $0.75 to $0.95. That is a few cents cheaper than digipaks and other CD wallets. However, if large quantities of cases are needed, the price difference may be hundreds or thousands of US dollars.[citation needed]

Weaknesses

There are a number of shortcomings with the jewel case. The case is hinged on two brittle plastic arms, which often break if the case receives shock or stress due to being dropped. The teeth of the hub holding the disc are also prone to failure by snapping. There is a problem with the tabs ("half-moons") which hold the liner notes in place; sometimes, especially with larger booklets, the tabs grip the booklet too tightly, leading to tearing. When replacing the booklet, it can get snagged and crumple or rip. As noted above, some CD releases have only two tabs, which allows the booklet to be more easily removed and replaced (with the disadvantage of the booklet sometimes falling out if held the wrong way). Replacement jewel cases can be purchased, to replace those that have broken plastic arms or hub teeth.[citation needed]

Variations

Double disc albums can either be packaged in standard-thickness jewel cases with hinged media trays which can be lifted to reveal the second disc (trays hinged on the left are known as "Smart Tray" format; those hinged on the right are known as "Brilliant Box" format) or in a "double jewel case", sometimes called a multi-CD jewel case, "fatbox", or "Bookbox", which is slightly larger than two normal jewel cases stacked on top of each other, and can hold 2 to 6 CDs. Double jewel cases do not fit in some CD racks; however, some racks have a few extra wide slots specifically to accommodate them.[citation needed]

Jewel cases for CDs released early in the format's life featured frosted top and bottom spines as opposed to the ridged ones more commonly used. As a result of their rarity, these types of jewel cases are fairly coveted among collectors.[3]

"Super Jewel Box" is a more advanced design which offers amongst other improvements a greatly strengthened hinge area. The depth of the disc tray is also greater, allowing for two discs to be placed on top of each other. The super jewel box cannot be used as a direct replacement for the older jewel case design as its card insert for the back is slightly different in size and shape. The super jewel box was developed by Philips[1] and it was intended to be successor to the original jewel case. Some CD manufacturers (for example the high-end company Linn) are supplying them. The super jewel box is the conventional case for Super Audio CD (SACD) releases;[1] a taller "Plus" size, midway between CD and DVD-Video size, is the conventional case for DVD-Audio, and as of mid-2006, the case format for all albums released by the Universal Music Group in Europe.[4]

Many alternatives to the standard jewel case may also be found, including larger DVD-style cases with a more book-like shape. It is not uncommon to find CDs housed in custom cases, tins and boxes of varying shapes and sizes. Slipcases and other envelope-type designs are also occasionally used.[citation needed]

Some DualDiscs are packaged in jewel cases of a somewhat different design from the CD version; the inside edge is rounded instead of flat, and the physical position of the disc is moved slightly toward the spine to make room for a latch mechanism. The overall dimensions of a DualDisc case are roughly the same as a standard CD case. However, the hinge mechanism is smaller and cannot be dismantled as easily as on a standard jewel case.[citation needed]

Smaller jewel cases are used for 8 cm CD and DVD media; similar cases without the hub are used for MiniDisc and (magnetic) Zip disk media.[citation needed]

Additionally, larger jewel cases that were around the size of VHS keep cases were used for North American releases of games for the Sega CD, all western releases of Sega Saturn games, and games released early in the original PlayStation's life cycle. Because the larger thickness of these cases put the CDs inside at greater risk of being accidentally knocked out of their hubs, large foam bricks were placed on top of the discs when packaged to hold them in place.[citation needed]

Slimline jewel case

A "black side" Slim Case.

Slimline jewel cases first gained popularity as cases for CD singles sold in Japan and Europe, and have become a common space-saving packaging for burned CDs. The cases used for CD Singles sold in Japan and Europe are 7 mm thick, with a "J-card" type inlay, showing cover art through the front of the case, and also through both the spine and part of the back of the case. The CD itself is usually inserted "upside-down" in the case, so that the artwork on the disc itself shows through the transparent back of the case.[citation needed]

Most slim jewel cases sold for burned CDs use the measure 142 by 125 by 5 millimetres (5.59 in × 4.92 in × 0.20 in), which is roughly half the thickness of a standard CD jewel case, allowing twice as many CDs to be stored in the same space, and will generally fit two to a slot in a standard CD rack. They generally do not have room for a full package insert booklet, only a slip of paper for a track listing or cover art, showing only through the front of the case. Unlike the standard jewel cases, slimline cases are made of two pieces rather than three and do not have a place for a back label. However, with this design the "spine" is narrower, making the discs more difficult to identify when stored on edge on a shelf.[citation needed]

The bulk of slimline cases are made with translucent or transparent polystyrene, and are available in multiple colors. A stronger alternative is made from semi-opaque, semi-flexible polypropylene which is strong enough to protect the disc, but flexible enough not to break easily. Also, the hinge mechanism is inverted compared to the standard-width case, with the pivot arms being attached to the lower part of the case rather than the clear cover side.[citation needed]

External marketing packaging

In the U.S. and Canada, the jewel box of a music CD was originally packaged for retail sale in a large cardboard box called a longbox in order to fit in store fixtures designed for vinyl records, offer larger space for display of artwork and marketing blurbs, and deter shoplifting. This box also enabled censorship if the store deemed a particular album cover potentially offensive to the public. This packaging was much-criticized as environmentally wasteful, and was eventually dropped by most retailers in the mid-1990s, though major record companies continued to ship CDs to wholesale clubs, such as Costco and Sam's, in longboxes into the 21st century.

Around 1994, the top wrap-around label sticker began to appear on most CDs, to make it easier to read what each CD was from the top without having to flip through them to see the front cover. These stickers were usually nothing more than informational labels and rarely would have any use in the marketing of the album. The wrap-around sticker also provided an extra seal, possibly as another theft deterrent.

A chiefly Japanese packaging addition is the inclusion of an obi strip, a J-card-esque paperboard slip wound around the left side of the case to show details such as the price, artist, etc. The obi strip is particularly useful in the case of Japanese releases of western artists' material, due to the fact that the cover artwork is unaltered from its original-language release.

Paper or Tyvek sleeve

Paper sleeve

The simplest, least expensive package is a paper envelope. More expensive versions add a transparent window to the envelope allowing the disc label to be seen. The envelope can also be made out of spunbonded polyethylene (trade-named Tyvek). This is both more durable and less abrasive than paper. However, such packaging is rare for commercial releases due to its relative lack of protection compared with other designs, and is primarily limited to promotional and demo discs.

It is also often used in software packages, where the box is labeled promotionally, but the disc comes in a paper sleeve (to cut costs).

Q Pack

The Q Pack was developed by the Queens Group Inc. in the mid-1990s as an alternative to regular CD jewel cases. (The Queens Group was purchased by Shorewood Packaging, who are part of International Paper). The Q Pack does not have a snap-in tray like a regular jewel case. It is characterized by the corrugated raised area where the top hinges to the back. Since Q Pack cases are not transparent, generally cover art is applied as a decal to the cover. Decals can also be applied to the inside front, on the tray underneath the hub and the back cover. A slot for an insert booklet is found inside the front cover as on typical jewel cases.

The Q Pack has become one of the calling cards of No Limit Records, who used it often in the mid-to-late 1990s.[citation needed]

Digipak/Digipack

A digipak

The term digipak (trademarked term)/digipack (generic term) refers to a particular type of CD case which essentially consists of a plastic CD tray glued inside a folding rectangle cardboard cover. Variations include where the disc sits on a hub or spindle inside. Though it once referred specifically to the patented Digi-Pak packaging, the term has since become genericized as digipack. Despite being made of paper, they were once considered an environmentally more friendly alternative to jewel cases though are vulnerable to shelf wear unless stored properly in plastic sleeves.

A taller form has been used for some DVD movie releases; it is essentially identical to the CD package, though with raised top and bottom sections to keep the disc from sliding out if it comes disengaged from the hub.

Digisleeve

A digisleeve is a rectangle cardboard package where the disc slides into the packaging.

Digibook

A digibook (a.k.a. mediabook) is a type of packaging that has a hard cover (like a hardbound book) and comes in various sizes. The disc can either slide into the package or sit on a spindle, hub or tray inside.

Mini LP sleeve

A mini LP sleeve (a.k.a. paper sleeve) is a square cardboard package that looks like a miniaturized version of an LP jacket. The disc slides into the jacket either into a pocket or any other opening. Mini LP sleeves can either appear as standalone cardboard sleeves or gatefolds, identically to full-sized LP jackets, with both variants being used for a number of music releases.

While used in a somewhat limited capacity in the west, where the jewel case remains the most popular form of CD packaging, mini LP sleeves are popular for reissues of older albums in Japan, with their typically high level of faithfulness to the original vinyl record packaging making them highly sought-after among collectors.

The downside to this format is that the disc can be easily scratched each time it is taken out for play; a more serious issue can also be that if the glue that keeps the sleeve that holds the CD closed on the side closest to the spine (on gatefold covers) weakens, it can get onto the CD, rendering it unplayable. For these reasons, mini LP releases typically feature the CD enclosed in a protective sleeve made from matted plastic or rice paper. Another disadvantage with mini LP sleeves is that, like digipaks, they are significantly more vulnerable to wear and other forms of damage compared to standard jewel cases and are more difficult to replace.

One advantage of mini LP sleeves is that album covers that were originally textured, such as Back in Black by AC/DC or Fear of Music by Talking Heads, can retain the texturing on the CD release, as well as being able to replicate other nuances of the vinyl packaging such as unusually shaped packaging or artwork intended to span the whole of a gatefold (i.e. Obscured by Clouds and The Dark Side of the Moon, respectively, by Pink Floyd). In addition, the packaging is more environmentally friendly due to the use of more easily recyclable and biodegradable cardboard (as opposed to the polystyrene used in jewel cases) and is significantly cheaper to produce than both jewel cases and digipaks, which has made them a more favorable option in a market where CD sales are gradually declining.

Minipack

A minipack is a square cardboard package in which the disc sits on a spindle, hub or tray. In essence, it's a combination of a digipak/digipack and mini LP sleeve. This type of packaging is not seen very often.

JakeBox

JakeBox is a 100% paperboard packaging concept designed in Sweden for CD, DVD and Blu-Ray discs, featuring a patented pop up "claw". The claw releases the CD when the cover is opened and locks it again by closing the cover. This innovative design not only creates an eye-catching way to opening and presenting the disc, making it easily accessible, but properly protects the CD once closed.[5][6]

Discbox Slider

The Discbox Slider (also called DBS) is a disc packaging concept in 100% carton board, found both in CD and DVD sized packaging formats. The DBS is comparable with plastic jewel or Amaray cases when it comes to size but holds more of the features of the LP style cases in terms of light weight and printability. The DBS case opens up from the side by moving the slider part (on which the disc is resting) from the sleeve. The Discbox Slider is 100% recyclable. Many covermount CDs released in British magazine Mixmag used to be packaged in Discbox slider,[citation needed] after replacing a standard jewel box, although the discbox slider itself was replaced by a simple cardboard sleeve.

Compac Plus

The Compac Plus is a disc packaging which is similar in style to a digipak. However, it consists of two plastic CD trays which "clip" together like a normal slipcase. The packaging was introduced in the early 1990s. It was originally a brand which had their own logo, and was used by bands such as Blur, but as years progressed, many other artists started to use their own version of the packaging. The packaging is also known as Compact Plus.

Keep case

A Keep case

A keep case is the most common type of DVD packaging and was created by Amaray. It is taller and thicker than a Jewel case, and is made of much softer, less brittle plastic (polypropylene rather than polystyrene), so it does not break as easily. They usually hold one or two discs, but are capable of holding up to six discs. Slimmer keep cases, so called "Slim-paks" or "Thinpaks" typically used for DVD box sets consisting of the thin keep cases stored in a paperboard box. The thin cases are half as thick and can generally only hold one disc as a result, but there are newer slim cases that have central disc holding teeth on both sides. The teeth are made in such a way that when the case is closed, they go between the gaps in between the teeth on the other side.

A standard DVD case is a single-piece plastic case with two creases, which folds around and snaps closed. It measures 135 mm × 190 mm × 14 mm (5.3 in × 7.48 in × 0.55 in). It is wrapped on the outside by a thin piece of transparent plastic which can hold a paper label. The label measures 284 mm × 184 mm (10.8 in × 7.25 in).

Some DVD releases have a paperboard outer sleeve around the shrinkwrap.

Beginning in 2007, prerecorded Blu-ray Disc and HD DVD titles ship in packages similar to but slightly smaller (18.5 mm shorter and 1 mm thinner: 135 mm × 171.5 mm × 13 mm.)[7] than a standard DVD keep case, generally with the format logo prominently displayed in a horizontal stripe across the top of the case (red for HD DVD and PlayStation 3 Greatest Hits Games, blue for Blu-ray, and clear for regular PlayStation 3 games). Green cases of this variety were introduced to be used for titles released for the Xbox One gaming system, though with the space intended for placing the disc being on the left side of the inner case, while most other keep cases have it on the right.

Snap case

A snap case is a design for both CD and DVD packaging, and is made in the standard sizes for both. Each is made of a single-piece plastic tray and closure, which snaps over the right edge of the front flap. The printed flap is made of thin paperboard which wraps around the left edge and across the back of the tray, to which it is glued. It has largely been replaced with the DVD keep case and CD jewel case due to its flimsy design. Warner Brothers and New Line Cinema were the only major film studios to release DVDs in this format.

Soft Case/Green case

Soft cases, also known as Earth cases or Green cases, are soft-shell cases made from recycled optical discs. They are considerably more pliable than other style cases given that they are made from various mixes of plastics. They are sold by various companies as replacements for disc owners who are environmentally friendly and can be differentiated from other cases by their opaque appearance. The softness of the cases leads them to break less, though the safety of the enclosed disc may be somewhat sacrificed since the case can be bent end-to-end easily.

ECO Pack

In 2006 Universal Music introduced the first completely paper-recyclable CD case, titled Eco Pack. Not only is the sleeve printed on recycled card, but the tray is also made an innovative International Paper product branded PaperFoam.[8] Universal used this packaging for issues in its 20th Century Masters - The Millennium Collection series after 2006.

Lift-lock case

A lift-lock case viewed from the side, showing the latch mechanism

Many gold CDs, including those from Mobile Fidelity, are packaged in lift-lock cases, a special type of case where the CD is lifted out of the case automatically and a latch unlocked when opened. The advantage of this design is that only the edges of the disc are handled when removing it from the case, and the disc is never subjected to any bending force while being removed. From the outside, they appear almost identical to a standard jewel case. They have the same dimensions as a standard jewel case, and use standard booklets and back cards.

Spindles and other bulk packaging

100-disc cake box and spindle

Blank CD and DVD media are often sold in bulk packages called spindles or, less formally, cake boxes. This type of packaging consists of a round, clear plastic cup that mates bayonet-style to a base with a central post that holds a stack of discs; dummy discs made of clear polycarbonate with no recording surface are often packed on the ends of the stack to avoid scratches from contact with the hard plastic of the packages. Such packages have been designed to hold anywhere from ten up to 100 discs, and offer the user multiple options for packaging the finalized disc.

TDK and Memorex have begun selling some of their blank media in what they refer to as "Snap n' Save" cases, essentially polyethylene cases designed to hold up to ten discs in a package.

Finally, some bulk packages of blank media forgo a permanent container completely, instead using a simple blister pack for small numbers of media, or bundling large numbers of discs in shrink wrap to reduce waste.

Shoplifting and theft deterrence

Retail stores have several strategies to deter shoplifting of CDs and DVDs. Some used CD and DVD stores keep the actual discs behind the counter, in plastic sleeves. The CD and DVD cases on the shelves for the customers are empty. Since the album cover art is still on the CD and the movie poster and information is still on the DVD case, the customers can still browse through the CDs and DVDs to make their selections.

In North America prior to 1993, CDs were typically packaged in longboxes, tall cardboard cases that occupied the same amount of vertical space as an LP sleeve; while the packaging was initially used to avoid having to purchase new, smaller shelves for storing CD jewel cases, they were also popular among retailers for their ability to deter theft as a result of the boxes' larger size. Over twenty years after the official phasing out of the longbox, the packaging style still sees use in some stores today for this reason.

Libraries that have CDs and DVDs for loan may put magnetic strips on the discs, which will sound an alarm if a patron tries to leave the library without having taken out the item(s). Library staff demagnetize the strips when the patron checks out the discs for rental and re-magnetize them upon the discs' return. Some stores selling new CDs or DVDs will keep particularly valuable or high-priced items in a locked display case or locked cage. Pawnshops may put Blu-ray discs in a locked glass case, as they are higher-priced than DVDs and are thus a more attractive target for theft.[citation needed]

Multi-disc albums

Record stores and consumer electronics stores sell albums or books that contain numerous soft plastic sleeves, which can be used to store CDs, DVDs, Blu-ray discs, video game discs, and other discs. Some of the small books or albums can hold 12 discs. Some of the large albums or books can hold over 90 discs. The owner can either keep the original packaging (cases, booklets, etc.) or discard them.
