PROBLEM TO BE SOLVED: To address data on a disk selectively by allowing an integrated micro file to have a magnetic disk supported rotatably to store data and a micro motor to drive the magnetic disk. SOLUTION: A micro motor 14 includes a rotor 16 integrated with a 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 a proper read/write head, that is, an access head 24 to write/read magnetically data. |
