Abstract: In the illustrated embodiment a video cartridge contains an endless loop record tape with a multiplicity of channels, and a pair of pivotal guide arms for holding a length of tape in a taut condition to facilitate loading of the cartridge with the tape threaded between a capstan drive assembly and a transducer head. The downward movement of the cartridge into the operative position serves to retract the tape guides clear of the operating tape path. A tape tension arm is provided along the tape path in the cartridge and is so arranged as to apply tension to the tape as the cartridge is unloaded from the transducing machine. The tape reel in the cartridge is suspended on a bearing ball so as to provide very low resistance to rotation.

Abstract: 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 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.
