Abstract

A method and apparatus for controlling a tape player/recorder for retrieving and playing prerecorded selections recorded thereon at spaced locations. According to the method and apparatus, the tape is played, a number indicative of tape position is generated, the tape position numbers indicative of the start and stop points for each selection recorded on the tape are stored in a memory, and the stored start and stop numbers for each selection are subsequently recorded on the tape whereby the tape may be removed from the player/recorder and subsequently reinserted into the same or another player/recorder. When a tape is inserted into a player/recorder, the start and stop numbers are read from the tape and stored in the memory whereupon the stored numbers may be utilized for locating selections on the tape to be played.
