ABSTRACT:
In an apparatus for recording and/or reproducing, in successive slant tracks on a record tape, an information signal comprised of at least an audio signal and an index signal for use in controlling transportation of the tape; the input audio signal is converted to a digitized form in which the audio data for a predetermined length of time is grouped as a plurality of data blocks which are recorded by a rotary head in a first part of a respective slant track on the tape, an index signal generator provides a coded index signal to indicate respective input information, such as, an absolute tape-position address counted from a predetermined reference position on the record tape, an index area signal is generated in predetermined timed relation to scanning by the rotary head of said first part of each slant track, and a control is responsive to the index area signal for supplying the coded index signal to a rotary head for recording by the latter in a second part of said respective slant track which is located adjacent an end of said first part of the respective slant track.
