Formats current at any point during the years 2000-2009

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.

LightScribe (2004 – 2013)

LightScribe was not a format as such, but a technology introduced by Hewlett-Packard in 2004 that allowed optical drives to laser-etch labels onto compatible media.

As well as a compatible LightScribe enabled drive, LightScribe drivers and suitable disc-burning software that supported LightScribe was required. Finally, a LightScribe compatible disc was needed. After burning data to the disc, the disc is turned over so the label side is face down, and the same laser that burnt data is used to etch the reactive dye coating of the disc.

LightScribe-compatible discs came in the form of CD-R, CD-RW, DVD-R, DVD-RW, DVD+R and DVD+RW. No Blu-ray discs were LightScribe compatible.

The LightScribe technology could only etch in monochrome, and it was possible for the design to fade over time, especially if the disk was exposed to direct sunlight. Etching a disc took a considerable amount of time; up to 30 minutes for a high-contrast image.

As of 2013, the technology was no longer promoted by Hewlett-Packard, but it is possible to obtain the software from elsewhere. Drive manufactures have now ceased making LightScribe enabled optical drives (optical drives in computers are under threat in general).

Enhanced CD (1994 – )

An enhanced CD (or ECD) is a Compact Disc that contains both audio content playable on a standard CD audio player, and multimedia content playable on a computer CD-ROM.

Introduced in 1994, the idea behind enhanced CDs was to offer the music buyer some extra bonus features using space on the disc that was unfilled by the music. This might take the form of music videos (similar to the earlier idea of CD Video), interviews, wallpapers, pictures, lyrics, or links to an artists website.

Rather confusingly, there were three different ways on combining the different content on the disc. Prior to 1996, enhanced CDs were created in one of two ways. One was to have the multimedia content in the first track, but this meant that track 1 needed to be skipped when played in a standard CD audio player or else the multimedia track could cause an unpleasant noise to be heard. A subsequent solution was to have the multimedia content in the pre-gap before track 1 (rather like the way a CD-i Ready disc worked). Both of these methods were known as ‘mixed-mode’, combining Red Book Digital Audio and Yellow Book CD-ROM information in a single ‘session’ on the same disc.

To get around the problems of mixed-mode discs, Philips and Sony released the Blue Book standards in 1995, and worked with Apple, Microsoft and the Recording Industry Association of America (RIAA) to develop them. This new standard specified multisession technology that used two sessions on the disc, the first one containing audio tracks, and the second one containing data that is invisible to CD audio players. In 1996, most enhanced CDs used mixed-mode with the multimedia in the pre-gap, but by 1997 most were using Blue Book standards. The only downside to the newer multisession technology was that CD-ROM drives made before 1996 might not recognise them if they were not multisession capable.

Enhanced CDs can usually be recognised the official ‘Enhanced CD’ logo recommended by the RIAA. They may also have the CD EXTRA logo (previously known as CD Plus), which was trademarked by Sony for use on Blue Book discs.

Later technologies like DVD-Audio or DualDisc tried to perform the same function of offering the music album with bonus material such as videos, but later albums often came instead with the videos on a separate DVD-Video.

DVD-10 / double-sided DVD (1998 – )

DVD-10 discs are double-sided, single-layer DVD-Video discs and are sometimes referred to as ‘flippers’ since they need to be turned over to access the content on the second side. The DVD-10 format is much less common than DVD-9 (single-sided, double-layered discs) but were used more in the early days of DVD-Video, before dual-layer disc production was widely supported. DVD-10 has a storage capacity for video of 9.4 GB (4.7 GB per side). Single-sided, dual-layer discs (DVD-9s) were a feature of the DVD standard from the start, but some early players did have problems with them or needed a firmware upgrade.

DVD-10s don’t feature any artwork on the disc apart from a small area near the spindle hole to indicate which side is which. This is a criticism of the format, along with the difficulty of avoiding finger marks and scratches on the playing surfaces of the disc.

Some DVD-10s contained the movie on one side and bonus material on the other, or a widescreen version on one side and a fullscreen version on the other but some discs did split the film into two parts so the disc needed to be turned during the film, rather like a LaserDisc. Some people reserve the term ‘flipper’ for DVD-10s where the main feature is split over the two sides.

It is possible to find double-sided, dual-layer DVDs (DVD-18s), but these are uncommon, and reportedly more liable to playback problems.

MPEG IMX (2001 – 2016)

MPEG IMX (also known as D10) was a standard-definition digital video cassette format introduced by Sony in 2001 and was part of the Betacam family of professional video formats. It was priced between Sony’s Betacam SX and the more expensive Digital Betacam, and was intended to compete with the Panasonic DVCPRO 50 system. As the name suggests, MPEG IMX recorded in MPEG video format, in case MPEG-2 using only I-frames and 8 channel audio.

Like other Betacam formats, tape width was ½ inch and cassettes were available in small or large form factors, with the S size holding up to 60 minutes of video, and the L size up to 184 minutes. To distinguish MPEG IMX tapes from other Betacam formats, the shells were coloured green. Metal particle tape was used.

All IMX video recorders could playback Betacam SX tapes, and some could playback Digital Betacam as well as analogue Betacam and Betacam SP tapes, the video from which could be encoded into MPEG-2 format. Only IMX tapes could be used for recording in IMX video recorders.

Like all Betacam formats, no new MPEG IMX video recorders are being made, having been discontinued in 2016.

Superbit (2001 – 2007)

Superbit was a variant on standard DVD-Video introduced in 2001 by the Columbia TriStar Home Entertainment division of Sony.

Superbit DVDs used a higher bit rate transfer process to optimise video quality, and always contained both a 5.1 Dolby Digital and DTS soundtrack. The actual increase in bit rate varied according to the space available on the disc, and the bit rate of the standard DVD version (which itself could vary). They were compatible with standard DVD players and so could carry the DVD logo. Due to the extra space required for video and audio data, bonus material is kept to a minimum or not included at all, though there were a handful of ‘Superbit Deluxe’ releases which carried the bonus material on a second disk. The menus were different to those on the standard DVD release, and were kept simple to save space.

Fewer than 60 titles were released in Superbit format, and Superbit releases typically only sold 2% of the amount of the standard DVD version.

By 2007, Sony was promoting Blu-ray and the Superbit line was dropped.

Secure Digital High Capacity (SDHC) (2006 – )

SDHC (Secure Digital High Capacity) is a variant of Secure Digital offering higher capacity and speed, and was introduced in 2006 as version 2.0 of the SD specification.

Devices that support SDHC cards will still work with standard SD cards, but at slower speeds. However, older devices designed to work with standard SD cards (usually made before 2007) will not usually work with SDHC cards.

Standard SD cards are available up to 2 GB, whereas SDHC cards are able to offer up to 32 GB.

SDHC cards are rated for speed, with Class 2, 4, 6, and 10 available. The class number relates to the MB per second write speed, so a Class 10 card should offer a minimum of 10 MB/second. Some devices may specify a minimum card speed requirement.

Luminous vinyl record (1978 – )

A small number of phonograph records have been pressed on luminous vinyl, two of the first being the 12-inch single version of Kraftwerk’s ‘Neon Lights’, and the Penetration album ‘Moving Targets’, both in 1978. Since then, a small number of releases have been made on luminous vinyl.

In normal light, the records look like standard coloured vinyl (usually white in colour, but some other colours have also been used such as yellow for Kraftwerk’s 1981 7-inch single of ‘Pocket Calculator’) but give off a phosphorescent glow in darkness. They glow brighter after being exposed to bright light for a while.

HDCAM SR (2003 – 2016)

HDCAM SR (Superior Resolution) was a professional high-definition digital video cassette format, introduced by Sony in 2003 as a higher quality variant of its existing HDCAM system.

Like other Betacam-related formats, HDCAM SR cassettes were available in large and small sizes, and had the same tape lengths as Digital Betacam (up to 40 minutes for S and 124 minutes for L tapes).

It used higher particle density tape allowing an increased bit rate (a choice or 440 or 880 Mbps). Like HDCAM, it was commonly used in high-definition television production.

Sony HDCAM SR tapes were black with a cyan lid and contained a 1K memory chip to store metadata about the tape.

In 2016, Sony announced that it was ceasing production of its remaining ½-inch video tape recorders and players, including those for the HDCAM SR format.

HDV (2003 – 2011)

HDV was a high-definition digital video format for camcorders. Because of its high quality, it has been used for broadcast television as well as amateur video recording. JVC was the first company to release a HDV camcorder in 2003, with Sony and Canon producing camcorders later.

HDV video can be recorded at 720p and 1080p, sometimes referred to as HDV1 and HDV2 respectively.

Although special HDV tapes are available, their use was not required as the tape formulation (Metal Evaporate) is the same as standard MiniDV cassettes. One Sony camera could also use the large DV cassette format. HDV devices could usually play and record in DV format as well as HDV.

Accessories were available to allow HDV camcorders to record to non-tape media such as CompactFlash cards.

By 2011, Canon, JVC and Sony had discontinued their HDV products, and invested instead in fully tapeless formats such as XDCAM.
