ABSTRACT:
Main signals such as music and the like are read while auxiliary signals are simultaneously read from two sectors on a magnetic tape recorded in opposite directions using a tape reader having multiple heads. The read out signals are serially provided from a multiplexer and digitized by an A/D converter. A signal processing unit separates the digitized signals into main signals and auxiliary signals. A microcomputer carries out high speed search procedures using the auxiliary signals.
