Abstract
A tape drive which may accommodate tapes having a servo control track thereon as well as tapes without such tracks advantageously uses a lockout to prevent unwanted head translation when operating in an open loop mode. The lockout may be accomplished by energizing a voice coil motor to fix the head position, driving the voice coil motor to a fixed stop positioning the head, or latching a rocker connected to the head, thereby preventing movement of the head. The latching/unlatching function may be accomplished by driving an actuator supporting the beam springs, head and latch to an end-of-track position to similarly unlatch the rocker and return the assembly to a servo controlled mode of operation.
