スク用ヘツドのロツク装置。 A locking device that moves the head in the radial direction and brings it into contact with the hard disk, and holds the head in a landing zone when not in use, and has a shipping arm that rotates in conjunction with the movement of the head. In the device in which the head is biased to be moved toward the landing zone by a biasing member via a member, an actuating plate having an abutment portion that abuts the arm is attached to the shipping member. The actuating plate is rotatably mounted, and latching means is provided for latching the actuating plate to the shipping member such that the abutment portion abuts the arm, and the shipping member is unlatched against the biasing means. An electromagnetic magnet is provided to hold the shipping member in the operating position, and when the arm is rotated so that the head is moved to a side opposite to the landing zone, the shipping member is moved to the non-operating position via the actuating plate. When the arm is rotated so that the head is held by the electromagnetic magnet and moved to the side opposite to the landing zone, the abutting portion is pushed by the arm and the latching means is activated. A locking device for a hard disk head, characterized in that the plate is unlatched and the abutting portion of the actuating plate is moved to a non-abutting position where it does not abut the arm.
