ABSTRACT:
A method for playing a digitally recorded tape with a rotary head type reproduction apparatus in which selections which are recorded in unreproducible modes are automatically skipped. PCM-ID portions recorded in the PCM regions on the tape are detected to determine which regions on the tape are recorded in modes which are unreproducible by the particular reproduction apparatus. The detection operation may be performed during a rewinding operation. During the playing of the tape, the tape is quickly forwarded past selections which are found to be recorded in unreproducible modes. If no selections are found to be recorded in a reproducible mode, the tape cassette is automatically unloaded and ejected.
