Claims

[Claims for Utility Model Registration] (1) A cartridge holder that holds a disk cartridge containing a disk-shaped magnetic disk, and a magnetic disk inside the held disk cartridge by moving the cartridge holder up and down. Lifting means for loading and unloading disks onto and from the turntable; rotation driving means for rotationally driving the turntable; and writing and/or writing of signals on the magnetic disk.
or a magnetic head that performs reading, and a magnetic head support means that supports the magnetic head and supports the magnetic head so as to be able to approach and move away from the magnetic disk;
A magnetic disk drive is provided with a magnetic head transport means for transporting the magnetic head support means in the radial direction of the magnetic disk, and during loading, the magnetic head is lowered and brought into contact with the magnetic disk to write and/or read signals. In the apparatus, when the magnetic head is lowered during loading, the magnetic head supporting means is temporarily stopped during the lowering of the magnetic head supporting means, and after the stopping, the magnetic head supporting means is energized for a predetermined time to operate the operating shaft. 1. A magnetic disk drive device comprising: a solenoid for releasing the stop means by moving the solenoid; and a lock means for locking the stop means moved by the operation of the solenoid. (2) A magnetic disk drive device according to claim 1, characterized in that unlocking of said locking means is linked to the lifting operation of said cartridge holder.
