Abstract

PURPOSE: To search the heading of the unrecorded part of the tapelike recording medium automatically, by detecting that the no signal time continues for a prescribed time or more.
CONSTITUTION: Fast-feed reproducing is performed, and the reproduced output of magnetic head 6 is applied to signal deciding circuit 7. Deciding circuit 7 generates the signal output or the no signal output in response to presence or absence of the reproduced signal. If the duration of the no signal output of deciding circuit 7 becomes time T or more, signal generating circuit 8 generates the output, and this output is applied to microprocessor 9. Microprocessor 9 operates running control circuit 10 to control running control mechanisms 1 and 2 and inverts the running direction of tape recording medium 5 to perform rewinding reproducing. When deciding circuit 7 generates the signal output in this rewinding reproducing, processor 9 and control circuit 10 control running control mechanisms 1 and 2 to stop rewinding reproducing, and the tape recording medium is stopped.
