ABSTRACT:
A data storage device has a housing having a size and shape compatible with being inserted into a floppy disk drive. A data storage unit is provided within the housing for storing a plurality of floppy disk data images. A rotating hub is mounted in the housing to receive the spindle driven by the floppy disk drive. The rotating hub has a position encoder for generating a hub position signal. A transducer is mounted to the housing spanning a range of motion of the read/write head of the floppy disk drive. A head position sensor is mounted to the housing for generating a head position signal in response to a sensed location of the read/write head. A controller within the housing is responsive to the hub position signal and the head position signal to identify a position within a sector of a selected one of the floppy disk data images and to exchange data between the transducer and the identified position of the selected floppy disk data image in the data storage unit.
