Abstract:

A system for making customized multiple selection, multiple track magnetic tape records is disclosed. The records are made by recording the playback of separate selections with each being provided on a magnetic tape cartridge. The system includes a playback array for receiving and selectively playing back the cartridges in an order selected to provide the customization of the record, with at least two of the cartridges being played back simultaneously. One or more tape recorders are connected to the playback array and loaded with a supply of magnetic tape sufficient to provide at least one of the custom recorded magnetic tape records. Each tape recorder receives the playback of the array and records the playback on the magnetic tape supply to provide the custom record. A control circuit operatively connects to the array and to the tape recorder for starting playback operation of the array and recording operation of the tape recorder and for automatically switching the array to the next catridge in order in the array after each cartridge completes playback. The control circuit may include a tabulator for tabulating playbacks for each cartridge to account for royalties, and may further include variable length playback delay circuits to sequence selections of different lengths.
