<p><P>PROBLEM TO BE SOLVED: To provide a disk drive device which easily controls wobbling generated by rotation of a flexible disk. <P>SOLUTION: A disk drive device 100 for rotating a flexible disk 10 so as to reproduce and/or record information on the disk includes: a stabilization member 50 facing and near the surface of the disk for suppressing wobbling of the disk; an approximating member 70 for bringing the stabilization member surface and the rotating disk surface close to each other for each specific width; a differential pressure gage 60 for detecting a differential pressure of an air pressure in a gap between the stabilization member surface and the disk surface relative to the peripheral atmosphere; and a control part 90 for controlling the width of the gap between the stabilization member surface and the disk surface on the basis of the differential pressure detected by the differential pressure gage when bringing the stabilization member surface and the disk surface close to each other by the approximating member. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
