ABSTRACT:
A head retracting/latching apparatus for a hard or floppy disc drive includes a prong which is held during power-on conditions by an electromagnet at an unlatched position out of contact with the head assembly. When power is interrupted, the head assembly is energized to move the heads to a retracted "home" position. The prong is released by the electromagnet and moves by spring force towards a latched position contacting the head assembly to prevent its movement as long as power remains off.
