Abstract: An integrated data storage disk and disk drive assembly includes a rotatably supported magnetic disk for storing data. A rotor is fixedly joined to the disk for rotating the disk, and includes a plurality of rotor poles. A stator includes a plurality of stator poles positioned around the rotor for sequentially cooperating with respective ones of the rotor poles for rotating the rotor to rotate the disk. The disk and drive may be fabricated using lithographic and electroplating techniques, and a plurality of coaxial disks may be driven by a single disk drive in exemplary embodiments.

Abstract: PROBLEM TO BE SOLVED: To provide an integrated assembly of a data disk and a disk drive. SOLUTION: The assembly includes the magnetic disk for data memory, which is supported rotatable. A rotor including a plurality of rotor poles is fitted and fixed to the disk for rotating the disk. A stator disposed with a plurality of stator poles around the rotor is used for rotating the disk by rotating the rotor in turn connecting to each rotor pole. The disk and the drive can be formed by lithography or electroplate coating, and in a typical practiced case a plurality of coaxial disks can be driven by one disk drive.
