Abstract:
1. A tape drive comprising: a rotor compartment; means housed within the rotor compartment for coupling a rotor to a tape cartridge rotating a tape cartridge reel, and encoding a position of the rotor, the means including said rotor rotatably mounted within the rotor compartment wherein the rotor includes a first axial end, and a chuck feature at the first axial end; a magnetic code wheel attached to the rotor to spin with the rotor and located within the rotor compartment; a magnetic code wheel sensor stationarily positioned within the rotor compartment, which senses rotation of the magnetic code wheel; a printed circuit stationarily mounted in the rotor compartment, the sensor being mounted in the rotor compartment on the top surface of the printed circuit board, and the magnetic code wheel being mounted on the rotor above the top surface of the printed circuit board; and a rotatable shaft on which the rotor is fixedly mounted, the shaft extending through the rotor and protruding above the first axial end to form a chuck locating feature.
