Roland Music Style Card (1989 – 1991)

The Roland Music Style Card was a ROM card containing programmed music rhythms to extend those available in the E-series ‘intelligent synthesisers’ made by Roland.

The first of the ‘intelligent synthesisers’ was the E-20, released by Roland in 1988 as the first product of Roland’s new European arm, and was aimed at the high-end home market. A number of variations of the first-generation E-series were released, such as the cut-down E-5, and the enhanced E-30 and Pro-E (an ‘intelligent arranger’).

For the first generation of the E-series, the cards were prefixed with TN-SC1 and there were 14 Music Style Cards in the first series released between 1989 and 1991.

There was a subsequent series of Music Style Cards with a slightly different shape and prefixed TN-SC2 for later E-series synthesisers such as the E-35, E-56 and E-70.

DASH (Digital Audio Stationary Head) (1982 – mid-1990s)

Sony introduced the DASH (Digital Audio Stationary Head) in 1982 for use in professional recording studios. The DASH system could record two-channel audio on ¼-inch tape, or 24 or 48 tracks onto ½-inch tape, and DASH recorders were produced by Sony, Studer and TASCAM.

The tape itself looked identical to standard NAB open reel analogue tape, but tape for use in DASH and the competing (and incompatible) ProDigi format systems used metal-particle tape which was not suitable for use in analogue systems due to the faster wear on the heads. Several companies produced open reel metal-particle tape for digital audio systems, and some examples included 3M Scotch 275, Ampex 467, EMTEC 931 and Sony own-brand tape. Metal-particle tape was even more expensive than oxide-based tape for analogue systems.

Unlike some other digital audio recording systems using tape such as DAT or U-Matic which used helical scanning, the DASH and ProDigi systems used a stationary recording head.

The audio was encoded as PCM, and included error correction, and all DASH recorders were capable of using 16-bit resolution with a 44.1 or 48 kHz sampling rate, with a couple of models capable of 24-bit 48 kHz operation.

DASH and ProDigi were the two main open-reel digital audio recording systems in use from the early-1980s to the mid-1990s, but eventually the falling price of hard-disk space, as well as more compact systems such as ADAT, made them less viable.

Although DASH was a digital system, it still had the disadvantage of having to wind through the tape to find a particular point, and wear could still be a problem. Poorly maintained machines or tape, dust, or fingerprints could render tapes unusable despite the error correction system.

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.

Yaboom MCD Musical Key Chain (1999 – 2001)

Yaboom was a toy manufacturer of the late 1990s and early 2000s that specialised in celebrity musical dolls. It also made a couple of different formats for music, one of which was the MCD Musical Key Chain which was a small music player on a key chain.

Like similar formats such as HitClips, it was aimed at the teenage market. And like HitClips, sound quality was poor but the single songs were at least full length. As well as a play button, there was a switch that meant a 20 second sample was played when the play button was pressed, and this allowed users to hear a sample before buying as the play button could be pressed whilst the device was still in its packaging. There was no volume control and no headphone socket so the song could only be played through the tiny built-in speaker.

Artists such as Backstreet Boys, Britney Spears, TLC, B*Witched and Five were released on MCD Musical Key Chains.

Yaboom also made the Yaboom Box, a very small replica boom box on a key chain, that could be used with tiny interchangeable cartridges.

Yaboom appeared to have ceased trading sometime in 2001.

Nintendo Game Boy Advance Video (2004 – 2007)

Game Boy Advance Video was a means of watching video on the Nintendo Game Boy Advance handheld game console and was first introduced in 2004. The video came on ROM cartridges that looked similar to standard Game Paks, except they were always light grey and had a film perforation design on the label.

The Video Paks offered digital video with a resolution of 240 x 160 and full colour, but due to the low capacity of the cartridges the video was very compressed and of poor quality. The cartridges could also be used in the Game Boy Advance SP, Game Boy Micro, Nintendo DS, and Nintendo DS Lite systems. They could not be played on the Game Boy Player add-on for the Nintendo Game Cube (the low resolution would have become even more apparent on a television screen) because the Game Boy Player could be attached to a VCR or DVD recorder, so the ability to play video was disabled to prevent illegal copying of Game Boy Video material.

Content was mostly in the form of cartoons from Nickelodeon, Cartoon Network, Disney, and also by Nintendo themselves with the Pokemon cartoons. Some full-length animated feature films were released by DreamWorks Animation, namely Shark Tale, Shrek, and Shrek 2. Around 25 cartridges were released, with the last ones released in 2007.

Copy-protected Compact Disc (2000 – 2006)

The original specification for Compact Disc Digital Audio, known as the Red Book, did not make any provision for copy protection, and by the late 1990s millions of ripped audio tracks from Compact Discs were compressed as MP3s and shared over the internet.

The music industry did several things to try and rectify the situation, including setting up online music stores selling music through a subscription model, and the Recording Industry Association of America also prosecuted over 20,000 individuals they accused of sharing pirated MP3s.

Starting around 2000, the music industry also began to put copy-protection onto audio Compact Discs. Companies such as EMI, Sony, BMG, and for a time Warner used copy protection as a means to prevent ripping of audio tracks onto a computer.

Since the discs were non-compliant with the Red Book standard, they were not supposed to display the Compact Disc Digital Audio logo on either the disc or inside the jewel case. There was also a consumer outcry against the disks as they prevented tracks from being copied to the purchaser’s personal audio devices, and some CD players such as those in cars would not play the disks (since these sometimes used some CD-ROM components, especially if they were intended to play disks containing MP3 or other types of compressed files).

In 2005, it was discovered that Sony BMG were using a type of copy protection called Extended Copy Protection (XCP) which installed a rootkit on a user’s computer. This sparked a scandal as it could be used by malware, and Sony announced a recall of disks using XCP and suspended its use.

EMI was the last major label to abandon copy protection in 2006.

Yaboom Box (1999 – 2001)

Yaboom was a toy manufacturer of the late 1990s and early 2000s that specialised in celebrity musical dolls. It also made a couple of different formats for music, one of which was the Yaboom Box which was a very small replica boom box on a key chain, that could be used with tiny interchangeable cartridges.

This was very similar in concept to HitClips, and was aimed at the teenage market. Like HitClips, sound quality was poor, and the songs only lasted for one minute. Artists such as LFO, Sisqó, Christina Aguilera, Aaron Carter and Mandy Moore have been released on Yaboom cartridges.

Yaboom also made the MCD Musical Key Chain that contained a full-length song but without interchangeable cartridges.

Yaboom appeared to have ceased trading sometime in 2001.

CD-i Ready (1991 – 1998)

CD-i Ready was a hybrid optical disc format, combining audio tracks readable by any Compact Disc audio player, and multimedia or interactive elements readable on a CD-i (Compact Disc Interactive) player. It was introduced by Philips in 1991.

The audio tracks conform to Red Book Compact Disc Digital Audio standards, while the CD-i part conforms to Green Book standards, and could contain interviews, photos, biographies, games and more. The CD-i component is located in the ‘pre-gap’ area before track 1, which is skipped over by Compact Disc audio players.

The idea, like CD-i generally, was not a commercial success, and there appear to be fewer than 20 titles released as CD-i Ready discs.

The ideas behind the hybrid CD-i Ready discs were used in later types of hybrid audio/data discs such as the Enhanced CD that contained content which could be read on a standard computer CD-ROM drive rather than requiring a dedicated CD-i player.

MQS (2013 – )

Mastering Quality Sound is a term used by the South Korean company Astell&Kern to describe 24-bit high-resolution audio files that use the FLAC format (a lossless compression format). Astell&Kern sell a range of high-end audio players that support a range of audio file types, including high-resolution FLAC files, and the players themselves incorporate microSD card slots.

Music files can be transferred from a computer to the player using microSD or microSDHC memory cards of up to 32 GB, or connecting via cable, but a small number of pre-recorded albums have been released on microSD cards marketed under the name MQS.

MQS microSD cards contains high-resolution audio files in FLAC format and these can be played back on many devices in addition to Astell&Kern’s players, although additional plugins or apps may sometimes be required on other devices. Astell&Kern products support 24-bit high-resolution audio with a sampling rate of up to 192 kHz (though the music on MQS microSD cards varies from 44.1 kHz to 192 kHz depending on the source) and claim that this gives up to 6.5 times the level of detail of a conventional CD-quality audio file.

Pre-recorded music has already been released on microSD cards, both under SanDisk brands such as Gruvi and slotMusic, and also on generic microSD cards. These formats used MP3 files rather than the higher quality FLAC though.

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.
