Claims

[Claims for Utility Model Registration] (1) A magnetic disk rotatably provided in a housing, a magnetic head for writing and reading information to and from the magnetic disk, and a magnetic disk including the magnetic head. In a magnetic disk device comprising an actuator that moves in a radial direction and a drive motor for the actuator, a cam that rotates integrally with the rotation shaft of the drive motor, and a cam that is rotatably provided on a fulcrum and that moves toward and away from the cam. an arm that can be connected to a power source, and when the power source is turned off, the arm is brought into contact with the cam via a spring;
The cam is rotated to a predetermined position by the force of the spring to transfer the magnetic head to a predetermined position on the magnetic disk, and when the power is turned on, the arm is rotated against the force of the spring to rotate the cam. and a solenoid arranged so as to be spaced apart from the cam to a position where it does not interfere with the cam. (2) The magnetic disk device according to claim 1, wherein the rotation of the cam is stopped by a stopper provided at a predetermined location. (3) Utility model registration claim 1, characterized in that when the cam rotates to a predetermined position when the power is turned off, the arm engages with the cam to prevent movement of the magnetic head. The magnetic disk device described.
