ABSTRACT:
A positioning apparatus used for information-storage devices provides stoppage of a motor-driven transducer head-positioning lead screw follower as the follower approaches the motor-driven end of the lead screw. An element is provided on the follower which contacts a stop carried by the lead screw when the follower arrives at a position spaced from the motor by a predetermined distance, to thereby prevent the follower from moving any closer to the motor than such predetermined distance.
