ABSTRACT:
A magnetic tape cartridge is compatible with a disk drive, which comprises a cartridge casing defining a thin space, a pair of tape reels onto which a magnetic tape is wound and means for defining a path for the magnetic tape along which a portion of the tape is exposed at a location at which data can be transferred between the tape and the disk drive head. The tape reels are associated with a drive mechanism for selectively driving one of the tape reels for driving the tape between the tape reels. The drive mechanism includes a center core driven to rotate by means of a turntable. The drive mechanism further includes a power train including reel drive gears designed to drive associated tape reels and an input gear drivingly connected to the center core so as to be driven by the turntable. The input gear is associated with means for selectively meshing the input gear to one of the reel drive gears depending upon the direction of rotation of the center core.
