Digital Audio Tape Vector Logo Download
Sony developed the Digital Audio Tape (DAT) in the middle 1980s as a signal recording and playback medium. In a glance, the medium is similar to compact audio cassette which used the 4 mm magnetic tape enclosed in a protective shell, but definitely has the half size with 73 mm × 54 mm × 10.5 mm dimensions.
As the name defines, the recording is keep in digital format rather than analog. The Digital Audio Tape has the ability to record at higher, equal or lower sampling rates than a CD at 16 bits quantization. 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 MiniDisc, both of which use lossy data compression.
The technology of DAT is closely based on that of video recorders, using a rotating head and helical scan to record data. This prevents DATs from being physically edited in the cut-and-splice manner of analog tapes, or open-reel digital tapes like ProDigi or DASH.
