Digital Audio Tape (DAT or R- DAT) is a signal recording and playback medium developed by Sony and introduced in 1. As the name suggests, the recording is digital rather than analog. DAT has the ability to record at higher, equal or lower sampling rates than a CD (4.
Hzsampling rate respectively) at 1. If a digital source is copied then the DAT will produce an exact clone, unlike other digital media such as Digital Compact Cassette or non- Hi- MD Mini. Disc, both of which use a lossy data reduction system. Like most formats of videocassette, a DAT cassette may only be recorded and played in one direction, unlike an analog compact audio cassette, although many DAT recorders had the capability to record program numbers and IDs, which can be used to select an individual track like on a CD player. Although intended as a replacement for analog audio compact cassettes, the format was never widely adopted by consumers because of issues of expense and concerns from the music industry about unauthorized high- quality copies. The format saw moderate success in professional markets and as a computer storage medium, which was developed into the Digital Data Storage format.
As Sony has ceased production of new recorders, it will become more difficult to play archived recordings in this format unless they are copied to other formats or hard drives. History. This prevents DATs from being physically edited in the cut- and- splice manner of analog tapes, or open- reel digital tapes like Pro. Digi or DASH. The DAT standard allows for four sampling modes: 3. Hz at 1. 2 bits, and 3. Hz, 4. 4. 1 k. Hz or 4.
Hz at 1. 6 bits. Certain recorders operate outside the specification, allowing recording at 9. Hz and 2. 4 bits (HHS). Some early machines aimed at the consumer market did not operate at 4. Hz when recording so they could not be used to 'clone' a compact disc. Since each recording standard uses the same tape, the quality of the sampling has a direct relation to the duration of the recording . Included in the signal data are subcodes to indicate the start and end of tracks or to skip a section entirely; this allows for indexing and fast seeking.
Two- channel stereo recording is supported under all sampling rates and bit depths, but the R- DAT standard does support 4- channel recording at 3. Hz. DAT tapes are between 1. DAT tapes longer than 6.

Denon's development dated from its work with Japan's NHK Broadcasting; NHK developed the first high- fidelity PCM audio recorder in the late 1. Denon continued development of their PCM recorders that used professional video machines as the storage medium, eventually building 8- track units used for, among other productions, a series of jazz records made in New York in the late 1. In 1. 97. 6, another digital audio tape format was developed by Soundstream, using one inch (2. Honeywell acting as a transport, which in turn was connected to outboard digital audio encoding and decoding hardware of Soundstream's own design. Soundstream's format was improved through several prototypes and when it was developed to 5.
Hz sampling rate at 1. Telarc Records of Cleveland, Ohio. Telarc's April, 1.
Holst Suites for Band by Fred Fennell and the Cleveland Wind Ensemble was a landmark release, and ushered in digital recording for America's classical music labels. Soundstream's system was also used by RCA. Starting in 1. 97. M introduced its own line and format of digital audio tape recorders for use in a recording studio. One of the first prototypes of 3. M's system was installed in the studios of Sound 8.
Minneapolis, Minnesota. This system was used in June 1. Aaron Copland's . Paul Chamber Orchestra conducted by Dennis Russell Davies.
That record was the first Grammy- winning digital recording. The production version of the 3. M Digital Mastering System was used in 1.
Ry Cooder's . These systems used the EIAJ digital format, which sampled at 4. Hz at 1. 4 bits. The Sony PCM- F1 system debuted in 1. Sony from the start offered the option of 1.
Other systems were marketed by Akai, JVC, Nakamichi and others. Panasonic, via its Technics division, briefly sold a digital recorder that combined an EIAJ digital adapter with a VHS video transport, the SV- P1. These machines were marketed by consumer electronics companies to consumers, but they were very pricey compared to cassette or even reel- to- reel decks of the time. They did catch on with the more budget conscious professional recordists, and some boutique- label professional releases were recorded using these machines. These systems digitized an analog audio signal and then encoded the resulting digital stream into an analog video signal so that a conventional VCR could be used as a storage medium. One of the most significant examples of a PCM adaptor- based system was the Sony PCM- 1. The PCM- 1. 60. 0 used a U- Matic- format VCR for its transport, connected to external digital audio processing hardware.
It (and its later versions such as the PCM- 1. Digital Audio CDs in the early 1. Once CD's were commercially introduced in 1. PCM- 1. 60. 0 were sent to the CD pressing plants to be used to make the glass master disc for CD replication. Other examples include dbx, Inc.'s Model 7. Super Audio CDs, used a high sample- rate delta- sigma modulation rather than PCM; Decca's 1. PCM system. The DCC was cheaper and simpler mechanically than DAT, but did not make perfect digital copies as it used a lossy compression technique called PASC.
However, DCC proved that high quality digital recording could be achieved with a cheap simple mechanism using stationary heads. Anti- DAT lobbying. Initially, the organization threatened legal action against any manufacturer attempting to sell DAT machines in the country. It later sought to impose restrictions on DAT recorders to prevent them from being used to copy LPs, CDs, and prerecorded cassettes. One of these efforts, the Digital Audio Recorder Copycode Act of 1.
Sen. Waxman), instigated by CBS Records president Walter Yetnikoff, involved a technology called Copy. Code and required DAT machines to include a chip to detect attempts to copy material recorded with a notch filter. A National Bureau of Standards study showed that not only were the effects plainly audible, but that it was not even effective at preventing copying. This opposition by CBS softened after Sony, a DAT manufacturer, bought CBS Records in January 1. By June 1. 98. 9, an agreement was reached, and the only concession the RIAA would receive was a more practical recommendation from manufacturers to Congress that legislation be enacted to require that recorders have a Serial Copy Management System to prevent digital copying for more than a single generation.
However, the computer industry successfully lobbied to have personal computers exempted from that act, setting the stage for massive consumer copying of copyrighted material on materials like recordable CDs and by extension, filesharing systems such as Napster. In this configuration, it is possible for the audio to remain digital from the first AD converter after the mic preamp until it is in a CD player. Pre- recorded DAT.
Later in May 1. 98. Wire released their album The Ideal Copy on the format. Factory Records released a small number of albums on the format, but many planned releases were cancelled.
It sold well in Japan, where high- end consumer audio stores stocked DAT recorders and tapes into the 2. However, there and in other nations, the technology was never as commercially popular as CD or cassette. DAT recorders proved to be comparatively expensive and few commercial recordings were available. Globally, DAT remained popular, for a time, for making and trading recordings of live music (see bootleg recording), since available DAT recorders predated affordable CD recorders. Computer data storage medium. It is a sequential- access medium and is commonly used for backups. Due to the higher requirements for capacity and integrity in data backups, a computer- grade DAT was introduced, called DDS (Digital Data Storage).
Although functionally similar to audio DATs, only a few DDS and DAT drives (in particular, those manufactured by Archive for SGI workstations). SGI DDS4 drives no longer have audio support; SGI removed the feature due to . Although it is being superseded by modern hard disk recording or memory card equipment, which offers much more flexibility and storage, Digital Data Storage tapes, which are broadly similar to DATs, apart from tape length and thickness on some variants, and are still manufactured today unlike DAT cassettes, are often used as substitutes in many situations. In 2. 00. 4, Sony introduced the Hi- MD Walkman with the ability to record in linear PCM. Although the Hi- MD format did find some favour as a disc- based DAT alternative for field recordings and general portable playback, Hi- MD manufacture ended in 2.
