ABSTRACT:
A translatable capstan/tachometer assembly for use, for example, in transporting a magnetic media in a data record/reproduce apparatus, includes a capstan rotatably coupled to a tachometer unit. The assembly is supported for movement from an initial, unthreaded media position within a threading cavity of a data cassette, to a threaded or locked working position. The media path is arranged so that moving the capstan/tachometer assembly into the threaded position causes the media to wrap around the capstan with a substantial wrap angle. In play, record, jog or variable speed operational modes, movement is provided between a motor/disc assembly and the capstan/tachometer assembly to rotatably drive the capstan. In a high speed shuttle mode, the motor/disc assembly is disengaged but the capstan/tachometer assembly remains in contact with the media, thereby still providing tape speed information via the integral tachometer unit.
