Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention uses a plurality of unit recording / reproducing devices such as a hard disk drive and distributes and records input data such as video and audio to the plurality of unit recording / reproducing devices to transfer the data. The present invention relates to a recording / reproducing device capable of achieving high speed and the like.

[0002]

2. Description of the Related Art A recording / reproducing apparatus is known in which a plurality of hard disk drives are connected to each other and the plurality of hard disk drives are operated in parallel to increase the transfer rate of the recording / reproducing apparatus. ing.

11 to 13 are a plan view, a side view and a front view showing the conventional recording / reproducing apparatus. The recording / reproducing apparatus 101 includes a plurality of hard disk drives 102 ...
102 is a case called a caddy 103 ... 10
103 into which the hard disk drive 102 is inserted, and the case 103 ... 103 into which the hard disk drive 102 is inserted into the case insertion portion 105 of the apparatus main body 104. Guides 106 for guiding the case are provided on the upper and lower surfaces of the case insertion portion 105, and rails 107 are provided on the upper and lower surfaces of the case 103. The case 103 includes the guide 106 and the rail 107 so that the case insertion portion 10 of the apparatus main body 104 can be accommodated.
When the case 103 is inserted into the case insertion portion 105, the rear side (the rear end side) of the case insertion portion 104 is inserted into the case insertion portion 105 with good operability and smoothly. The connector 109 on the apparatus body side and the connector 110 on the case side, which are provided on the rear side panel 108 arranged in the above, are connected.

The case insertion portion 105 of the apparatus main body 104
The front end of the case 103 inserted into the device is supported by the front panel (sub-front panel) 121 of the apparatus main body 104 by the case fixing means 111. The case fixing means 111 is the case 103.
Front stay 112 at the front end of the
Is connected to a panel (sub-front panel) 121 on the front side of the apparatus main body 104 with screws 113. A handle 131 is provided on the front side of the case 103.

[0005]

In the conventional recording / reproducing apparatus, as described above, the guide 106 and the rail 1 are used.
07, guides the sliding of the case 103, and the case fixing means 111 fixes only the front end of the case 103 to the front panel (sub-front panel) 121 of the apparatus main body 104. Therefore, there were the following problems.

(1) In order to slide the case 103, as shown in FIG.
7, between the guide 106 and the upper and lower surfaces of the case 103, and between the rail 107 and the upper and lower surfaces of the case insertion portion 105, predetermined clearances C1, C2, and C3 must be provided, respectively. The front side is fixed to the front side panel (sub-front panel) 121 of the apparatus main body 104 by the case fixing means 111.
Since the rear side of 03 is not fixed, the case 103 moves up and down and left and right (in the directions of arrows E and F in FIGS. 13 to 14) due to the vibration generated by the hard disk drive 102 itself and the vibration transmitted from the device body 104 side. Vibration causes the control system to go off and causes off-track, which causes seek errors, recording / playback errors, etc.
It causes a serious defect in the disk array.

(2) When the recording / reproducing apparatus is subjected to an acceleration in the up / down and left / right directions due to an impact during transportation or in use, the rear side of the case 103 is displaced in the up / down and left / right directions.
The shock acceleration is transmitted to the hard disk drive 102,
Eventually, a force is applied to the connectors 109 and 110, which causes deterioration of electrical contact.

(3) The problems of the above (1) and (2) are to reduce the clearance C1 between the guide 106 and the rail 107 or to increase the fixing strength by the case fixing means 111. However, in order to reduce the clearance C1 and the like, it is necessary to improve the dimensional accuracy of the parts, and in order to increase the fixing strength of the case fixing means 111,
The stay 112 provided on the case 103 has to be large in size or the number of screws 113 must be increased, which causes an increase in cost.

The present invention has been made for the purpose of solving the above conventional problems.
