Formats current at any point during the year 2010 onwards

1.8-inch hard disk drive (1991 – 2014)

The 1.8-inch hard disk drive was introduced by Integral Peripherals in 1991, and had up to two platters for a maximum storage capacity of 320 GB on the last model introduced by Toshiba in 2009.

The 1.8-inch form factor of hard drive was not popular at first, despite being the same form factor as the PCMCIA card, making it suitable for use as removable storage on laptops with a PCMCIA slot.

It eventually came to be used for internal storage in compact laptops such as netbooks, and in the original version of the Apple iPod, later known as the iPad Classic, which was discontinued in 2014.

The 1.8-inch hard disk drive is no longer produced, having been replaced in the kind of devices that would have once used it by solid-state drives.

DVCPRO (1995 – early 2010s)

DVCPRO (also known as DVCPRO25 or D-7) is a variation of the DV format, and was introduced by Panasonic in 1995 for professional and broadcast use.

In common with all DV formats, DVCPRO uses tape that is ¼-inch (6.35 mm) wide, but DVCPRO uses metal particle (MP) tape rather than metal evaporate. DVCPRO also adds an analogue audio cue track and a control track to make editing easier.

DVCPRO50 was introduced in 1997 and used two DV codecs in parallel, doubling the data rate over the original DVCPRO to 50 Mbps. DVCPRO50 decks can use DVCPRO tapes, but the tape is run at twice the speed so capacity is halved.

In 2000, Panasonic launched DVCPRO HD for high-definition recording. This had a data rate of 100 Mbps and competed with Sony’s HDCAM.

Panasonic stopped selling equipment using video tape around 2013.

White label vinyl record (1948 – )

White label vinyl records are generally 12-inch LPs, or 7-inch singles and come with a plain centre label (usually white) and are in plain packaging. The centre label might have handwritten details of the artist and title, or may be rubber stamped, or have a sticker applied.

Some white label records are test pressings made by the pressing plant, usually in quantities of 5 or less,  and then listened to to check the sound quality before pressing larger runs.

Some white label records are produced for promotional purposes, including advance copies sent to retailers or to DJs. Sometimes white labels are used to conceal artist identities, so the record is listened to without prejudice. Dance music producers might produce white label copies to play in dance clubs to gauge crowd response.

Other white label records are unofficial or partially unofficial releases, for example if a remix was made without the consent of the artist or label.

Generally, white label records are not distributed to the general public.

Ultra Density Optical (UDO) (2003 – )

Ultra Density Optical (UDO) is an optical disc data storage format that uses phase-change, and blue laser technology (similar to Blu-ray) to store substantial amounts of data on a disc in a cartridge very similar to the older 5.25-inch magneto-optical disc format that it was developed to replace.

UDO discs were first announced by Sony in 2000, and launched by Sony and Plasmon in 2003 with a capacity of 30 GB. UDO 2 was launched in 2007 with a capacity of 60 GB.

UDO discs are available in rewritable format, or as write once in which case the phase change method used means the data cannot altered once written (True WORM) making it very stable for long-term storage. A third format became available in 2005, Compliant WORM, that allows specific data on the disc to be destroyed while leaving other files intact.

As of 2017, UDO drives and discs are still available but since 2008 all brands of UDO disc have been manufactured by Mitsubishi in Japan.

Interactive DVD (1998 – )

Interactive DVDs (sometimes also known as DVD games, DVD Interactive or DVDi) allow the playing of games on DVD-Video players without the need for a computer or video game console, or any additional hardware (though some titles come with additional hardware such as buzzers).

The interactive DVD make use of the rudimentary interactivity features built-in to DVD-Video players that allow, for example, navigation through menus. The ability to skip to any point on the DVD instead of having to move through the video in a linear fashion as on VHS video recorders is also a major factor in making interactive DVDs practical.

The first interactive DVD game was Dragon’s Lair released in 1998, and a development of an older LaserDisc based game.

From 2001, DVD versions of board games and television quiz shows began to be released.

LP (Long Play) 12 inch record (1948 – )

The LP (Long Play) record is an audio format for phonograph records, introduced by Columbia Records in 1948 and still in use today.

LP records are made of vinyl (either virgin or recycled) and together with a playing speed of 33⅓ rpm and the use of microgrooves, allow for a playing time of around 45 minutes. Previously, 78 rpm records had a playing time of just around 3-4 minutes per side, so an ‘album’ of records was sold as a set, and this name continued to describe a collection of songs on a single disc.

Each side of an LP contains a single continuous groove, with an average length of 460 m.

LP records are generally 12 inches in diameter, but 10 inch LPs have also been produced at different times. The amount of vinyl in an LP is generally 130 g, but some records were produced with less (sometimes as little as 90 g). Modern high-fidelity LPs tend to use more, such as 180 g. Generally LPs are pressed on black vinyl, but coloured vinyl and picture discs (with a card sandwiched between two clear sides of vinyl) have been produced, as have shaped vinyl and even neon vinyl.

By as early as 1952, LPs represented 16.7% of unit sales, rising to 24.4% in 1958 (by then, most of the remainder was 45 rpm singles, 78 rpm only representing 2.1%).

Stereo sound was introduced in 1958, and quadraphonic records were sold in the 1970s for a time.

The LP had no serious competitors for long-playing recordings until the 1970s when the Compact Cassette improved in quality, and then in the 1980s with the introduction of the Compact Disc. LPs ceased to be a mainstream format in the early 1990s, but continue to be produced in small but increasing numbers.

35mm film (1892 – )

35mm film was the most common film gauge for cinematography, and was also used in still photography (in the form of 135 film).

The name derives from the width of the film strip. When used for motion pictures, the image is across the film and each frame usually has four perforations giving 16 frames per foot, whereas when used for photography the image is lengthways along the film and each frame uses eight perforations. In conventional motion picture film, the image is 22 x 16mm (known as the ‘Academy ratio’). The shape and frequency of the perforations differed in the early years.

The 35mm format was introduced in 1892, soon after the introduction of transparent flexible film in 1889,  at a time when a large range of different film gauges were in use. By 1909 it became accepted as the international standard gauge and remained so until largely replaced by digital cinematography. Although other gauges have been used for cinematography, 35mm remained the most popular with professional film makers as it provided a good trade-off between cost and image quality.

Until the 1950s, 35mm film was made of cellulose nitrate which was highly inflammable and difficult to extinguish once alight. It was replaced with ‘safety film’ (cellulose triacetate). From the 1990s, film stock was made with a synthetic polyester safety base.

Sound was introduced around 1926, with Warner Bros. using synchronised phonograph discs. Later sound-on-film systems include optical analogue, optical digital, and magnetic strips. DTS soundtracks use a timecode printed on the film to synchronise with Compact Discs.

Between 2005 and 2015, most cinemas rapidly converted to digital projection, and in 2014 Paramount Pictures announced that it would no longer supply 35mm prints of movies in the US. Whilst 35mm film is still in use for both shooting and showing movies, it is rapidly becoming a niche format.

Shaped Compact Disc (1996 – )

Shaped Compact Discs first appeared in the mid-1990s, the first being The Flaming Lips Compact Disc single entitled ‘This Here Giraffe’ released in 1996 on a 8-pointed star-shaped disc.

The most common form of shaped Compact Disc is the business card sized CD-ROM introduced in 1998, but shaped CDs can come in a variety of shapes. Generally, Compact Disc audio discs can be symmetric or asymmetric, whereas shaped CD-ROMs are generally symmetrical so they do not cause vibrations in high-speed CD-ROM drives.

Shaped CDs contain less audio or data than standard 12cm discs, and may not work in all drives.

View-Master Virtual Reality Experience Pack (2015 – )

The View-Master Virtual Reality Experience Pack is designed to be used with the View-Master Virtual Reality Viewer introduced by Mattel in 2015 – a headset that holds a smartphone and allows the viewing of 3D virtual and augmented reality images via an app.

There are a number of Experience Packs available as of 2017, including educational titles such as ‘Destinations’, ‘Wildlife’, ‘Dinosaurs’ and ‘Space’, as well as some entertainment titles such as ‘Batman’ and ‘Masters of the Universe’. Each pack contains a Pass Card to activate the app, and three ‘reels’. The Virtual Reality Viewer also comes with a preview reel.

The reels, which are made to look a bit like the original View-Master reels, do not contain any information but trigger the app to display an augmented reality icon above the reel when viewed through the Virtual Reality Viewer, and the user can then select the reel to view virtual reality content. Unlike previous versions of the View-Master, the reels are never inserted into the device and it’s possible to access the Experience Pack contents without the reels, which merely act as a menu system.

7-inch EP (1952 – )

The 7-inch EP (for Extended Play) was a format introduced in 1952 by RCA Victor, just a few years after the introduction of the 7-inch single format in 1949.  It sat between the 7-inch single and the 12-inch Long Play (LP) record, and like the 7-inch single it span at 45 rpm so could be played on any photograph with a 45 rpm setting.

By using narrower grooves, it was possible to squeeze 7½ minutes of playing time on each side at the expense of volume, allowing more than one song on each side (generally EPs have between three and six tracks). Like LPs, EPs did not necessarily have ‘title’ tracks, and could have different names to the songs on them (for example the 1963 Beatles EP simply called ‘The Beatles’ Hits’).  They were also packaged more like an LP with a cardboard picture sleeve, whereas 7-inch singles until the 1970s generally had paper sleeves with just the record label on them.

Whilst less common in the US, the 7-inch EP was widely sold in the UK and some other European countries, and between 1960 and 1967 they were popular enough for Record Retailer magazine in the UK to compile a separate EP chart. They were a good way for artists to produce something more substantial than a single between LP releases.

They declined in popularity after the 1960s, and faced competition from formats such as 10-inch and 12-inch singles or EPs (which could allow for more sound volume with wider grooves), as well as Cassette and CD singles or EPs. However, small numbers of 7-inch EPs are still released.
