Patent ID: 7864472

Claim:
A data storage device comprising: a housing having a size and shape compatible with being inserted into a floppy disk drive, wherein the floppy disk drive has a spindle and a read/write head; a data storage unit within the housing for storing a plurality of floppy disk data images; a rotating hub mounted in the housing to receive the spindle driven by the floppy disk drive, the rotating hub having a position encoder for generating a hub position signal; a transducer mounted to the housing spanning a range of motion of the read/write head of the floppy disk drive; a head position sensor mounted to the housing for generating a head position signal in response to a sensed location of the read/write head; and a controller within the housing 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.
