creator Camras, Marvin creator Galus, Stanley A. In the illustrated embodiments a rotary head indexing cam has a power drive train releasably coupled therewith for automatic head indexing with a manual channel selector driven by the power drive train during automatic indexing while being manually operable to select a given channel independently of the drive train. A fine channel adjustment control is operable to shift the indexing cam axially for fine adjustment of head position relative to a selected channel. A latch retaining the capstan drive in operating position is mechanically released as the head completes scanning of a succession of chennels (sic) on the record tape. Capstan pressure rollers on hinged arms are swung through an open end of an endless loop cartridge to engage the record tape with the capstan, a predetermined bias being applied to the pressure rollers to press the same toward the capstan in the operating position.
