The design of a new tape transport system is analyzed, which was developed for use in a professional stereo recorder. Except for a few mechanical moving parts and five optical sensors, the entire operation is controlled electronically. A microprocessor-based system commands all the transport functions, including multiple-point search, by means of nine memories through a calculator-type keyboard. It features constant tape tension and several advanced characteristics. The equations of the tape movement and the theoretical optimization of the fast search to cue algorithm are also given.
