ABSTRACT:
A dual capstan tape transport mechanism having a magnetic tape trained along a path for movement successively between an upstream capstan and pressure roller, past record and play heads, and between a downstream capstan and pressure roller. A motor drives the downstream capstan directly and drives the upstream capstan indirectly, and slightly slower, through an overrunning clutch. Separate solenoids move the pressure rollers to press the tape against the respective capstans. The mechanism is selectible to play either an improved dual capstan type cartridge with both capstans, or to play a conventional single capstan type cartridge with the downstream capstan alone. Tape guide posts, aligning the tape and providing wrap around the heads, and a shield engageable with the backside of the tape opposite the play head, are movable with the upstream pressure roller through openings in the housing of the dual capstan cartridge.
