Abstract :
A method to double the search speed and the data transmission rate for recording/reproducing has been studied for a DAT (digital audio tape recorder). A high speed search up to 400 times the normal playback speed was realized. Using this DAT, the search time for programs from the beginning to the end of a 2-hour long tape was reduced to 26 sec from 44 sec, the latter value being that for a conventional DAT. With this technology, a high-speed search system has been developed for a DAT using magnetic tape as the recording medium
