ABSTRACT:
A method for detecting playing time of a magnetic tape in which a video signal is recorded includes the steps of computing a plurality of residual time data obtained by detecting the instantaneous position of the inserted magnetic tape while performing a high speed winding search mode and high speed rewinding search mode while the tape is loaded on a cassette tape deck of a VCR. Thus, it is very easy to recognize the playing time of the tape including a video signal.
