Claims

[Claims for Utility Model Registration] (1) A motor and a belt-wrapping shaft rotated by the motor, the central portion of which is wound around the circumferential surface of the belt-wrap shaft, and the end portion of which is secured to a head carriage. and a belt-shaped drive transmission member that converts the rotation of the head carriage into linear movement of the head carriage, and the belt-shaped drive transmission member is attached to a single strip part and a side part of the single part with a width slightly larger than the width of the belt-shaped drive transmission member. A disk drive comprising a pair of parallel double-striped portions with a wide interval, and the width of the single-striped portion and the sum of the widths of the paired double-striped portions are set to be equal. head carriage drive mechanism. (2) By wrapping the center part around the peripheral surface of the motor and the belt-wrapping shaft rotated by the motor, and fixing the end part to the head carriage, the rotation of the belt-wrapping shaft is converted into the linear movement of the head carriage. A belt-shaped drive transmission member that can be changed is provided, and a locking pin provided on the head carriage side is inserted into a pin insertion hole provided at an end of the belt-shaped drive transmission member, and the end of the drive transmission member is changed. A head carriage drive mechanism for a disk drive, characterized in that the locking pin is configured to be fixed to a head carriage, and the lower surface of the head of the locking pin is formed into a tapered surface that slopes while decreasing in diameter toward the distal end side.
