As shown in the figure, a plurality of magnetic disk disks are attached to a spindle 2, and a magnetic head 4 is attached to an arm 3 facing the magnetic disk disk 1. The arm 3 is attached to the shaft 5 of the carriage, and there is a carriage bobbin 6 attached to the lower shaft 5. The carriage bobbin 61 is provided with a fill 7, and the coil 7 is connected to the upper and lower magnets 8. A carriage bobbin 6 is rotated by a coil 7 and a magnet 8 located between the coils 7 and 8.

ックしている。なお、１４は側板である。The magnetic head 4 floats up due to the rotation of the magnetic disk disk, reads/writes information on the magnetic disk disk 1, and when the rotation of the magnetic disk disk 1 stops, the magnetic head 4 descends and touches the magnetic disk disk. There are so many. When the head comes into contact with the disc, such as when it rises or falls, it is carried out on a data-free surface (C8S zone) in order to mine data. Therefore, in order to prevent the data surface from being damaged due to vibration of the magnetic head 4 and magnetic disk disk 1 during transportation of the magnetic disk device, the head must always be in the C8S zone.
Conventionally, the bin 1o of the carriage bobbin 6 is pushed against a stopper 11 by a thumbscrew 13 to lock the carriage bobbin 6. Note that 14 is a side plate.

Since the operation was performed manually, the cover had to be removed, which was troublesome. In addition, in many cases, multiple magnetic disk drives M are housed in a rack, and therefore, the thumbscrew 13 is operated after pulling out the magnetic disk drive from the rack and removing the cover. Opening and closing operations were difficult and problematic.
