A magnetic tape storage device used in the backup of large amounts of data which conforms to the DDS standard. The cartridges can store from 2 to 20 GB of native or uncompressed data with an archiving rate of 2 Mbps. See Digital Data Storage (DDS), Linear Tape Open (LTO), Digital Linear Tape (DLT), Advanced Intelligent Tape (AIT), Digital Versatile Disk (DVD), Jukebox and Magneto Optical Disk (MOD).

This type of magnetic tape, introduced by Sony, at one point threatened to supplant the normal audio cassette with a better quality alternative. Unfortunately,...

Format for the storage of digital data. Most commonly available using a rotary-head mechanism (R-DAT) similar in principle to that of a video recorder.

Any magnetic tape that's been used to record digital information. The tape itself isn't any different than tape used to record analog signals with the exception of being of a very high quality.

(DAT) Medium for storing digital rather than analog data.

DAT. A method of recording information in digital form on a small audio tape cassette.DATs can be used as backup media.

DAT is currently the standard professional digital format for 2-track digital recording. DAT was sold to at the consumer level but wasn't a commercial success. As digital recorders have no tolerance for clipping, using a DAT recorder takes a slightly different knack. The results can be worth it; however, as the DAT format offers the same resolution and dynamic range as CDs. Digital recorders can record for up to 3 hours on a tape.

Digital audio format stored in binary form on a small cassette. Music can be recorded digitally with this format (some restrictions do apply to prevent excessive duplication).

Digital Audio Tape. A method developed by Sony and Hewlett-Packard for recording large amounts of information in digital form on a small cassette tape.

Digital Audio Tape (DAT or R-DAT) is a signal recording and playback medium developed by Sony in the mid 1980s. In appearance it is similar to a compact audio cassette, using 4 mm magnetic tape enclosed in a protective shell, but is roughly half the size at 73 mm × 54 mm × 10.5 mm. As the name suggests the recording is digital rather than analog, DAT converting and recording at higher, equal or lower sampling rates than a CD (48, 44.1 or 32 k Hz sampling rate, and 16 bits quantization) without audio data compression.
