[0022]
The portable disk module-side rotation screw portion 112 provided in the portable disk module 100 collides with the housing-side protrusion 116 when the portable disk module 100 is inserted. Unless it is rotated, the portable disk module 100 is not inserted. The housing-side protrusion 116 also serves to protect the magnetic disk device 103 from an impact force with an unstable insertion force caused by human power. Here, the portable disk module side rotation screw portion 112 is held by a portable disk module side rotation screw receiving portion 128. Moreover, the screw part 112 has a helical screw shape as can be seen from the illustrated structure.
[0023]
The configuration shown in FIG. 3 shows an outline of a mechanism for converting the rotational motion of the portable disk module side rotating screw portion 112 by the operation of the operation handle 104 into the linear motion of the portable disk module. Details of the conversion motion from rotation to straight line are shown in FIGS.
[0024]
FIG. 4 shows a portable disk module inserted into the casing 101 of the magnetic disk subsystem by inserting the operation handle 104 into the portable disk module side rotating screw portion 112 attached to the portable disk module 100 according to the embodiment of the present invention.

In this state, it is inserted into the housing 101 of the disk subsystem. The portable disk module rotating screw part 112 abuts on the housing side receiving part protrusion 116 provided in the housing 101 of the disk subsystem and is prevented from progressing in the insertion direction.
[0029]
Next, in order to insert and drive the portable disk module 100, the operation handle 104 is inserted into the operation handle hole 113 and rotated to operate the portable disk module rotation screw portion 112. Since the rotating screw portion 112 is fitted in the housing side receiving portion screw escape hole 125 and the screw portion 112 has a helical shape, the screw portion 112 is screwed along with the rotation in the direction of the arrow 127. The portable disk module integrated with the unit is driven in the forward direction so that the connector 106 and the connector 107 are electrically connected. In FIG. 4, the rotating screw portion 112 is illustrated, but known means for converting the rotational movement of the handle into the linear movement of the portable disk module is also an example of the configuration of this embodiment.
[0030]
