Abstract
An interlock for a disk drive unit having a handle and a camming arrangement responsive to pivotal movements for inserting and withdrawing the unit from a housing fixture. A solenoid is actuable to lock the handle when the unit is fully inserted. A sensor is adapted for sensing an interlock engagement between the solenoid armature and the handle. For removing the disk drive unit, a delay is interposed before retracting the solenoid armature to assure that the disk drive unit is fully stopped before the handle can be rotated for removal of the unit.
