Method of recording/reproducing table of contents in digital magnetic tape recording/reproducing apparatus

A recording method for recording a table of contents (TOC) in a digital magnetic tape apparatus, in which a head performs a helical scan of a magnetic tape to form tracks and each track includes a pulse code modulation (PCM) area for recording digital data and a subarea for recording a digital subcode signal representing information about the digital data, comprising the steps of:

• writing a TOC signal in a PCM area as an audio signal, in response to activation of a TOC button;
• and
• writing a TOC code signal, corresponding to the written TOC signal, in the subarea corresponding to the PCM area in which the TOC signal is written.

A reproducing method for reproducing a table of contents (TOC), in a digital magnetic tape apparatus, in which a head performs a helical scan of a magnetic tape to form tracks and each track includes a pulse code modulation (PCM) area for recording digital data and a subarea for recording a digital subcode signal representing information about the digital data, comprising the steps of:

• writing a TOC signal in a predetermined PCM area as an audio signal in response to activation of a TOC button and subsequent audio input;
• and
• storing a TOC code signal in a program memory of the digital magnetic tape apparatus in response to activation of a memory button during reproduction of a magnetic tape part, wherein the TOC code signal stored in the program memory is the one corresponding to the TOC signal being reproduced at the time of activation of the memory button, which was previously written in the subarea corresponding to the PCM area containing the reproduced TOC signal.

• writing a TOC signal in a predetermined PCM area as an audio signal in response to activation of a TOC button and subsequent audio input;
• and
• performing a high speed search for a data area designated by a TOC code signal, and reproducing the searched data, in response to activation of a search button during reproducing of the TOC, the searched data including the TOC code signal being written in the subarea corresponding to the PCM area in which the TOC signal, being reproduced at the time the search button is activated, is written.

• and
• inhibiting a recording of a start code signal during the writing of the TOC signal in the PCM area.
