ABSTRACT:
Digital data is recorded on a magnetic tape by rotary heads. The magnetic tape has a PCM data recording area on which PCM data of a plurality of programs is recorded and sub-code recording areas on which sub-code data is recorded. On the sub-code recording areas of each program, character code data representing the title of the associated program and the like is recorded. On the sub-code recording area of the first program, pack data of a TOC mode is recorded. The pack data of the TOC mode includes character code data, and this character code data includes information recorded on the sub-code recording areas corresponding to all programs. By reproducing the pack data of the TOC mode by the rotary heads, character code data of all programs can be recognized.
