is installed on the front, making it possible to perform maintenance from the front.

[0010] Furthermore, connections to higher-level devices such as string control circuits and magnetic disk control circuits were made by connecting cables to the front.

[0011] This magnetic disk module 1 was mounted in a locker from both sides back to back, making it possible to perform maintenance on both sides.

0012

[Problems to be Solved by the Invention] However, the prior art has the following problems.

Four device-side connectors 8 are screwed to the rear plate 75 in correspondence with the module 1-side connectors 6 (see FIG. 6). By forming the screw hole of this device side connector 8 slightly larger, the device side connector 8
can move within a limited range.

A cable (not shown) to a string control circuit is connected to the back side of the device side connector 8.

In this module storage portion 73, the L-shaped drive storage portion of the module 1 is located in the module storage portion 73.
It is inserted deep into the L-shape of No. 3 and positioned, allowing the connectors 6 and 8 to face each other, making it easy to connect the connectors.

Moreover, since the device side connector 8 is movable,
Even if there are errors such as tilt in the manual plug-in operation,
This will be absorbed and the plug-in operation will be made easier.

Furthermore, when removing the module 1, it can be easily removed without applying excessive force to the connectors 6 and 8.

[0073] In this way, the plug-in operation of the module 1 enables easy connection to a host device, and since the front surface of the module 1 is open, replacement and expansion of the module 1 becomes easier.

Since the device-side connector 8 is movable, connector connection by plug-in operation of the module 1 is facilitated.

[0075] Since the module 1 is mounted on the locker 7 from the front and rear faces back to back, high-density mounting is possible.

Since the top and bottom of the module 1 are open, and the storage section 73 of the locker 7 is also open at the top and bottom, a duct structure can be formed that forms a cooling air passage in the vertical direction, and the cooling fan 7
2 improves cooling efficiency.

Since the connection with the string control circuit etc. is made on the back side of the module 1, there is no need for a connection cable on the front side of the module 1, and even if the module 1 is not installed in a part, the duct structure can be changed by closing the door. can be maintained and cooling can be done efficiently.

(2) Although the description has been made regarding a magnetic disk device, it can also be applied to other storage disk devices such as an optical disk device and a magneto-optical disk device.

The present invention has been explained above with reference to examples, but
Various modifications are possible within the scope of the present invention, and these are not excluded from the scope of the present invention.

[0083]

[Effects of the Invention] As explained above, according to the present invention,
It has the following effects.
