ABSTRACT:
A data recording method and apparatus for a magnetic recording medium, such as a magnetic tape for an R-DAT, in which the tops of the various music selections recorded on the tape are accurately detected so that reproduction can be started accurately. In one embodiment of the invention, program top detecting codes are recorded on the tape a predetermined time prior to the actual start of the music programs. In another embodiment, the program top detecting codes are recorded at the start of the respective programs. In the latter case, in a high speed search operation to find a desired music piece, when a corresponding program top code is detected, the commencement of reproducing the desired music piece is delayed for a predetermined period of time from the detection of the program top code, so that the reproduction is accurately carried out from the top of the desired music piece.
