Definition Edit

DAT (an acronym for Digital Audio Tape) is

a signal recording and playback medium for digital audio developed by Sony and introduced in 1987. In appearance it is similar to a compact video 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.[1]

Overview Edit

It is the tape counterpart to a CD that is smaller than the traditional cassette tape and permits double the recording time (two hours) of a normal CD. Unlike a CD, a DAT is susceptible to deterioration over time. However, the DAT has the capacity to record CD quality sound onto a cassette with ease.
