AB  - The rotary-head digital audio tape recorder (R-DAT), which was launched in the Japanese consumer market in March 1987, is the latest in a series of digital audio equipment which has appeared recently. Besides offering high-speed search, ease of operation, and other functional advantages, it boasts recording and playback performance well above that of conventional analog consumer recording equipment. Audio performance of the R-DAT is determined mainly by the quality of the A/D and D/A conversion circuits. This paper describes the application of an oversampling technique to both A/D and D/A conversion circuits in our first-generation R-DAT. A drastic improvement was achieved in the phase characteristics in the recording/playback processes, resulting in virtually identical recording and playback waveforms.
