ABSTRACT:
A method of recording/reproducing a table of contents in a digital magnetic tape apparatus, in which a head performs a helical scan of a magnetic tape to obtain tracks, each track including a PCM area for recording digital data and a subarea for recording subcode signals. In the recording, a reproduction skip signal is written in the subarea by a TOC button operation and a TOC signal is written in the PCM area of the tape itself as an audio signal. Also, a TOC code signal corresponding to the TOC signal is written in the subarea. When reproducing, the TOC code signal is stored in a program memory during the reproduction of the tape. A high speed search of program numbers or music titles and a data head position searching of the same are precisely performed.
