Abstract: PROBLEM TO BE SOLVED: To attain data write and read between a data storage magnetic disk and a stator having plural stator magnetic poles by including a data storage magnetic disk in which an integrated assembly between a data disk and a disk drive is supported rotatably. SOLUTION: A micro file 10 includes a magnetic storage disk 12 supported turnably and stores information in binary data bits. Each micro motor 14 is integrated with the disk 12, includes a rotor 16 integrated with the disk 12 as a one-piece assembly to drive the disk 12. The rotor 16 is extended radially outward and includes plural rotor magnetic poles 18 around the extended part of the rotor 16. Each micro motor 14 is provided with a stator 20 having plural stator magnetic poles 22 to be arranged on a circumference around the rotor 16 at an interval, to drive the rotor 16 in cooperation with each rotor pole 18 sequentially, to drive the disk 12 to allow an access head assembly 24 to write/read magnetically data.
