The authors have developed a prototype model of a Rotary-head Digital Audio Tape recorder (R-DAT) conforming to the specifications of the DAT conference. The prototype model realizes a rapid access music search system, recording, and playback capability of 48 kHz sampling rate, 16-bit linear conversion, playback capability of 44.1 kHz, and reliability using sophisticated error correction algorithms. This paper describes the signal processing and the performance of the R-DAT.
