A disk drive for use with a flexible magnetic disk having a sheet metal hub having a central hole and an eccentric slot formed therein. The disk drive has a turntable on which the disk is to be placed for joint rotation therewith. The turntable has a spindle disposed centrally for centering engagement in the central hole in the disk, and a drive pin disposed eccentrically on the turntable for driving engagement in the eccentric slot. Erected on the free end of a lever pivotally mounted to the turntable, the drive pin is movable substantially radially of the turntable. A magnetic member is also mounted to the free end of the lever for magnetically biasing the drive pin radially outwardly of the turntable so that the disk may be engaged by the spindle and the drive pin without looseness. For magnetically biasing the drive pin there is utilized a permanent magnet rotor which constitutes a part of a disk drive motor and which is mounted to the turntable for joint rotation therewith.
