In the removable disk device 20 in which the main body is also removable, the disk cartridge 5 is inserted and ejected, and the removable motor 2 chucks the disk 6 and rotationally drives it as in the conventional example. Thus, the head 8 of the actuator 3 writes a signal to the disk 6 or reads a signal from the disk 6.

Further, the conventional removable disk devices 1 and 20 have such a shape that the lamp 16 sandwiches the disk 6 in the disk cartridge 5.

Such a removable disk device 1,
As shown in FIG. 24, the ramp 20 has the disk 6
When the disc cartridge 5 is inserted, the disc 6 in the disc cartridge 5 enters the ramp 16. Thereafter, the disk 5 in the disk cartridge 6 is chucked by the magnet of the spindle motor. At this time, the disk 6 moves in the ramp 16 in the direction indicated by the arrow F in FIG. Further, when the disc cartridge 5 is ejected, the disc 6 is unchucked from the spindle motor.
