ABSTRACT:
A half height data cartridge tape drive mechanism includes a deck pivotally attached to a baseplate. An engagement lever is connected to pivot linkage to pivot the deck; to eject linkage to eject a cartridge in the tape drive; and to a cartridge door opening mechanism for opening the cartridge door in response to movement of the engagement lever into various positions. A drive motor is interconnected by a drive belt to rotate a capstan assembly. The capstan assembly engages a drive roller of a cartridge to cause movement of a magnetic tape in the cartridge. Indexing pins and slots engage the front corners of the cartridge and operate in conjunction with a center-of-gravity pad and tilt cam on the deck and an offset fulcrum and tilt stop on the housing to align with a magnetic head mounted on the deck. A head positioning assembly mounted on the deck includes a stepper motor with a worm gear attached to the motor's drive axle, a transfer beam is pivotally mounted to the deck at its center and is interconnected to the worm gear at one of its end for moving the one end vertically along the worm gear upon rotation of the drive axle by the stepper motor. A parallel fixture is attached to the deck at one of its ends and to the other end of the transfer beam at its other end. A magnetic head is mounted to the other end of the parallel flexure. A drive tire is stretched around the drive capstan to engage the drive roller of the cartridge.
