TORSIONAL ACTUATOR FOR LOADING AND UNLOADING FLEXIBLE DISK DRIVE Abstract of the Disclosure A torsional actuator is disclosed for loading and unloading a flexible disk drive. The actuator includes a torsion beam having a biasing arm and a plurality of actuating arms ex- tending therefrom with the free ends of the actuating arms being separately engageable with different ones of the collet, pressure pad and recording head arm of the flexible disk drive. The arms of the actuator are configured to enable selective and sequential movement of the collet, pressure pad and/or recording head arm in one direction toward a disk within the drive to establish a loaded, or operational) position and in the opposite direction away from a disk within the drive to establish an unloaded, or disk accessing, position with such positioning being determined by a force applying cam engageable with the actuator.
