Also, the rear panel 2 of the device body 2
b, a pair of openings (not shown) for inserting a power supply are provided, and the power supply unit 3 as a backup power supply can be freely inserted and removed from each of the openings for inserting the power supply. A connector (not shown) of the power supply unit 3 is connected to a connector (not shown) in the apparatus main body 2, and a current is supplied from one of the power supply units 3 to the apparatus main body 2.

Further, on a chassis 2c in the apparatus main body 2, a connector 5 for inputting / outputting scudgy (SCSI) is provided.
A, 5B, a scuzzy interface circuit board 6,
A circuit board 7 for a disk array controller (CPU) and a buffer memory, and a circuit board 8 for a memory of each hard disk drive 10 and a scuzzy protocol controller are arranged. On the back of each power supply unit 3, an inlet (not shown) into which an AC (AC) cord plug is inserted / removed is screwed, and a cooling fan 4 is screwed.

Can be replaced.

[0006]

However, in the above-mentioned conventional hard disk array device 1 ', when the operation of the power supply unit 3 and the hard disk drive 10 becomes abnormal and they are replaced during the operation of the device main body 2, When the caddy 20 or the power supply unit 3 is pushed in the directions of arrows A and B in FIG.
When the connectors (not shown) of the power supply unit 3 and the hard disk drive 10 are connected to the connectors (not shown) of the apparatus main body 2, impact vibrations are generated due to collision of the connectors, and the caddy 20 and the hard disk drive 10 are connected.

When the shock vibration acceleration is transmitted to the hard disk drive 10 through the caddy 20 without attenuation, the acceleration (FIG. 1)
6 (indicated by symbol C).

[0007] The hard disk drive 10 itself is also accelerated by a head access or the like (indicated by the symbol D in FIG. 16).
This acceleration is transmitted through the caddy 20 and the chassis 2c of the apparatus main body 2 to give an acceleration to the adjacent hard disk drive 10. At this time, the allowable acceleration value of the hard disk drive 10 is as small as 2 G for normal operation and 10 G for abnormal operation, for example. When the impact acceleration due to replacement of the caddy 20 or the power supply unit 3 exceeds the normal allowable value, data recording is performed. If the reproduction becomes an error and exceeds the abnormal allowable value, the hard disk drive 10 itself is broken, which may cause a serious defect in the hard disk array device 1 '. Furthermore, if the hard disk array device 1 'is accidentally dropped during transportation or the like of the hard disk array device 1', a large shock acceleration or vibration is applied to each hard disk drive 10, and the hard disk drive 10
There is a fear that the hard disk array device 1 'itself may be broken and serious defects may be caused in the hard disk array device 1' as described above.

In the case where the vibration of the caddy 20 is transmitted to the hard disk drive 10 or the adjacent hard disk drive 10 and vibrates, the head motion control system of the hard disk drive 10 may be off-track due to the vibration. This causes a seek error, a recording / reproducing error, and the like, and may cause a serious defect in the hard disk array device 1 '.

Incidentally, as a countermeasure for the above, FIGS.
As shown in FIG. 2, a pair of upper and lower vibration isolating rubbers 37,
Although a structure for arranging the anti-vibration rubber 37 is also conceivable, the structure of the anti-vibration rubber 37 of a type that holds substantially the entire circumference of the hard disk drive 10 is shown in FIGS. As described above, it was not possible to sufficiently cope with the case where the total length was different. In addition, as shown in FIGS. 17 and 18, when the fixing screw 36 of the outer casing of the hard disk drive 10 is engaged with the holding surface 35 of the caddy 20, a gap is formed between the holding surface 35 and the vibration isolating rubber 37. Then, it was difficult to sufficiently exhibit the anti-vibration effect.

Accordingly, the present invention provides a recording / reproducing apparatus capable of buffering an impact vibration acceleration when a caddy or the like is replaced or dropped, thereby further improving the reliability of the operation of the apparatus main body. .

[0011]

An opening for inserting a caddy is provided in a housing-type apparatus main body, and a housing-type caddy housing recording / reproducing means is taken in and out of the opening for inserting a caddy. In a recording / reproducing apparatus in which a connector and a connector in the apparatus main body are connected and detachable from each other, the recording / reproducing means is suspended via a damper in the housing-type caddy, and the damper is made of a metal having a U-shaped cross section. A plate, a vibration-proof rubber fixed to the metal plate, and a pair of mounting plates fixed to a pair of vibration damping portions before and after the vibration-proof rubber,

Each of the upper and both sides of the vibration damping rubber is integrally formed so as to protrude integrally therewith, and the upper and both sides of the vibration damping parts are respectively brought into contact with the caddy.

When a caddy or the like is exchanged during operation of the apparatus main body, the impact vibration acceleration tends to be transmitted to the recording / reproducing means. However, since the recording / reproducing means is suspended in the caddy via a damper, the recording / reproducing means is connected to the recording / reproducing means. The above shock vibration acceleration is buffered. Thus, even if a caddy or the like is replaced during operation of the apparatus main body, factors such as recording / reproducing errors of the recording / reproducing means due to impact vibration acceleration at the time of replacement are eliminated, and the operation reliability of the apparatus main body is further improved. Can be Also, even if the main body of the recording / reproducing device is dropped by mistake during transportation, etc., the vibration damping rubber of the damper may be destroyed because part of the upper and lower vibration damping parts function as stoppers. However, a stable buffering force is always obtained.

It functions as stoppers in the vertical and horizontal directions for preventing compression of a predetermined value or more, and comes into contact with the inner wall of the caddy 20, respectively. Anti-vibration rubber 3 of each damper 30
The horizontal and vertical shock vibrations transmitted from the caddy 20 to the hard disk drive 10 are buffered against the hard disk drive 10 by the spring constant and the damping rate of 2. Further, the shock vibration in the front-rear direction is buffered by each of the shear-type vibration damping portions 32a. Further, a vibration damping portion 32d in the form of a protrusion in the left-right direction.
The vertical projection-like vibration damping portion 32e always hits the inner wall of the caddy 20, and the repulsive force of the vibration damping portion 32e can always have the function of correcting the bias of the hard disk drive 10. By these, up and down, left and right,
The vibration damping portions 32a to 32e of the dampers 30, 30 in the three front and rear directions always provide vibration-proof characteristics with little variation.

Further, as shown in FIG.

According to the hard disk array device 1 of the embodiment described above, when data is recorded on a hard disk drive (not shown) of the hard disk drive 10, a signal obtained through the scuzzy interface substrate 6 is distributed by the circuit substrate 7, The data is recorded on the hard disk through the circuit board 8. Reproduction to the outside is the reverse of the above procedure. In this way, data is distributed to and recorded on the respective hard disks, and redundancy is secured by combining with a hard disk that records only the parity calculated from the data. Further, two power supply units 3 are used to support the redundancy, and even if one power supply unit fails, the other power supply unit can be operated by another backup power supply unit. The replacement of the power supply unit 3 (so-called hot swap) is performed easily and surely during the operation of (1).

As shown in FIG. 1, the hard disk drive 10 and the power supply unit 3 of the hard disk array device 1
Operation of the hard disk array device 1
When the hard disk drive 10 and the power supply unit 3 are replaced during the operation of the hard disk drive 10, the caddy 20 and the power supply unit 3 containing the hard disk drive 10
And B, when it is pushed into the inner wall of the apparatus main body 2, the connector 5 in the apparatus main body 2 and the caddy 2
The acceleration C transmitted to the hard disk drive 10 due to, for example, the connection of the two connectors 29 and the acceleration D also occurs when the hard disk drive 10 itself accesses the head and the like, and this acceleration causes the caddy 20 and the chassis 2 c of the apparatus main body 2 to be generated. Transmitted, adjacent hard disk drive 1
The effect of giving an impact vibration acceleration to the vibration damping part 32 of the pair of upper and lower dampers 30, 30 mounted between the hard disk drive 10 and the caddy 20.
a to 32e.

At this time, as shown in FIG. 8, the upper and lower gaps O between the hard disk drive 10 and the caddy 20 are small, and the mounting dimensions N and the total length M of the hard disk drive 10 are reduced.
6, as shown in FIG. 6, a pair of front and rear vibration damping portions 32 a, 32 of the shearing type of the vibration isolating rubber 32 of each damper 30.
If a gap V is formed in the vertical direction at an angle a, the gap V can be moved in the vertical movement, the influence of the spring constant is reduced, and the pair of front and rear vibration damping portions 32 of the shearing type is used.
A and 32a can form a damper structure in the front-back direction. Further, as shown in FIG.
Since the pair of mounting plates 33, 33 can be fastened and fixed to the caddy 20 by the respective screws 25B, the mounting conditions N, 0 are reduced, and the mounting dimension N of the caddy 20 in the front-rear direction is reduced.
Can be made smaller than the total length M of the hard disk drive 10, the caddy 20 can be reduced in size, and even if the total length M of the hard disk drive 10 changes, several types of hard disk drives can be used.

As shown in FIG. 2, by removing the screws 25B and the screws 25C, the hard disk drive 10 can be pulled out from the caddy 20 in the front-rear direction indicated by the arrow Y in FIG. Each piece 21-
24c has an integrally bent structure. This allows
The weight and cost of the caddy 20 can be reduced. Also, since each damper 30 is fixed to the hard disk drive 10 with the screw 34 and then put into the caddy 20, after each damper 30 is attached to the hard disk drive 10, the vibration isolating rubber 32 of each damper 30 is attached.
Thus, buffering on the hard disk drive 10 can be expected. Further, as shown in FIG.
There is a tolerance between the vertical dimension U of the vibration damping part 32c of each of the vibration damping rubbers 0 and 30 and the vertical dimension T in the caddy 20. In particular, the vertical dimension U of the vibration damping part 32c is Is smaller than the vertical dimension T of the
Since c is compressed from the initial state and the spring constant is high, the size is made smaller than the vertical dimension T in the caddy 20. In this case, a gap is generated between the caddy 20 and the damper 30 and the hard disk drive is Ten biases occur. Therefore, the left and right vibration damping portions 32d and the vertical vibration damping portions 32e of the vibration isolating rubber 32 always hit the inner wall of the caddy 20, and have a function of always correcting the bias of the hard disk drive 10 by the repulsive force. . Thus, each of the vibration damping portions 3 of the vibration isolating rubber 32 in the three directions of the vertical direction Z, the horizontal direction X, and the front-back direction Y.
With 2a to 32e, it is possible to obtain anti-vibration characteristics with little variation.

As described above, in the hard disk array device 1 according to the first embodiment, the pair of upper and lower dampers 30 as a floating suspension is provided between the hard disk drive 10 and the caddy 20, so that the hot swap or the like can be performed. With caddy 20 and power supply unit 3
Of the hard disk array device 1 can be further improved. Further, by making the shape of the pair of dampers 30 and 30 symmetrical, the upper and lower damper structures can be shared, and the cost can be further reduced by reducing the rubber mold cost and the types of parts. it can. Further, each damper 30 is obtained by fusing a vibration-proof rubber 32 to a metal plate 31, each damper 30 and the hard disk drive 10 are fixed by a screw 34, and the support is performed by the metal plate 31 of each damper 30, so that the hard disk drive 10 is fixed. Substrate 1 on the support surface
It can be used even with 7, 17 'or screws. The floating (suspension) support in the caddy 20 is performed by a pair of mounting plates 33 of each damper 30 fixed to the caddy 20 side.
33 and a pair of front and rear damping vibrating parts 32a, 32a to which these mounting plates 33 are fused, so that buffering in the front-rear direction Y can be performed regardless of the total length of the hard disk drive 10, and several types of hard disk drives can be used. The versatility (expandability) of the device 1 can be improved.

At the time of assembling, each damper 30 is fixed to the hard disk drive 10 with a screw 34, and in a state where each damper 30 is attached to the hard disk drive 10, as shown in FIG. Since the caddy 20 can be taken in and out, the caddy 20 can be formed by bending a metal plate, which is one part, so that the structure of the caddy 20 can be simplified and the cost can be reduced.
And the respective dampers 30 can be handled integrally, so that the hard disk drive 10 can be protected by the anti-vibration rubber 32 of each damper 30 and handling becomes easy. Also,
A projection-like vibration damping portion 3 that always projects into the caddy 20 against the anti-vibration rubber 32 of each damper 30 and protrudes in the left-right and up-down directions.
By providing the 2d and 32e, when the other vibration damping portions 32b and 32c of the vibration isolating rubber 32 are small relative to the caddy 20, the deviation of the tolerance can be corrected.

When the caddy 20 or the power supply unit 3 is replaced, the impact vibration is also transmitted to the adjacent operating hard disk drive 10 and the hard disk drive 10 moves in the caddy 20. Since it can be absorbed by the harness 13 and the flexible board 16 which relay the connectors 11 and 12 on the drive 10 side and the connection connector 29 on the caddy 20 side, good buffer characteristics can be achieved.

[Second Embodiment] FIGS. 10 to 12 and FIGS. 13A and 14A show a second embodiment of the present invention. In the second embodiment, a pair of dampers 3
Each vibration damping portion 32c above each of the vibration isolating rubbers 32 of 0 and 30
A portion 32c '(a pair of front and rear) of the handle 21a is arranged so as to be able to abut against each mounting plate 33 to serve as a stopper in the front-rear direction. The only difference from the first embodiment is that the surrounding portion 32e 'and the respective vibration damping portions 32b on both sides are stoppers in the vertical and horizontal directions for preventing compression of a predetermined value or more. Since the configuration is the same as that of the embodiment, the same components are denoted by the same reference numerals, and detailed description is omitted.

According to the second embodiment, in order to improve the reliability of the operation of the hard disk array device 1, a pair of dampers 30 as a floating suspension is provided between the hard disk drive 10 and the caddy 20. By providing the same, it is possible to attenuate the impact acceleration generated by replacing the caddy 20 or the power supply unit 3 by hot swap or the like, as in the case of the first embodiment. That is, as shown in FIG. 13 (A), when the hard disk drive 10 is displaced by the stroke G or more even if it is largely displaced in the front-rear direction Y, each mounting plate 33 is displaced.
The vibration damping portion 32 of the vibration isolating rubber 32 is
c ′ and the mounting plate 33 abut against each other,
2c 'serves as a stopper, and the hard disk drive 10
Of the vibration damping portions 32a, 32a of a shearing type can be prevented from being broken.

When the hard disk array device 1 having the vibration isolation structure is accidentally dropped or hit by another object during transportation or transportation, the hard disk array device 1 may hit the main unit 2 for more than 11 ms, for example. When a large impact acceleration having a peak acceleration value of 50 G or more or a vibration exceeding 2 G is applied, the hard disk drive 10 is largely displaced in the front-rear direction Y, but as shown in FIG. In the case of (1), since there is no stopper for stopping the displacement of the hard disk drive 10, the metal plate 3 of each damper 30 on the hard disk drive 10 side
1 is larger than the allowable deformation amount G in the front-rear direction Y from the mounting plate 33.
Only, it is deformed and a pair of front and rear vibration damping parts 3
2A and 32a may be destroyed.
As shown in FIG. 7, in the case of the second embodiment, the vibration damping portion 32c 'serves as a stopper to stop the displacement of the hard disk drive 10, and a pair of front and rear vibration damping portions 32a, 32a of a shearing type. Can be reliably prevented.

Further, when the hard disk drive 10 is largely displaced in the vertical direction, in the case of the first embodiment shown in FIG. 14B, there is no stopper around the vertical vibration damping portion 32e. The vertical vibration damping portion 32c is greatly deformed. In general, if the deformation of the compressed rubber exceeds 20%, for example, the rubber is torn due to excessive stress, so that the spring constant in the vertical direction changes, and there is a possibility that the vibration cannot be prevented. Therefore, FIG.
With respect to the effective length K of the vertical vibration damping section 32c in the case of the first embodiment shown in FIG. 14B, the vibration damping section 32 as a vertical stopper as shown in FIG.
By providing e ′ and setting the stroke L to the stopper to be equal to or less than 20% of the effective length K of the damper, excessive deformation of the vibration damping portion 32c can be prevented, and deterioration of each damper 30 can be reliably prevented. Since the stopper has a structure in which the position of the existing vibration damping portion 32c is changed or a stopper 32e 'is added, a countermeasure can be taken without affecting the anti-vibration effect such as a spring constant. Further, the same effect can be obtained by providing the same stopper 32b in the left-right direction as in the up-down direction.

Thus, for vibration in the front-rear direction,
By using a part of the vibration damping part 32c 'of the vertical vibration damping part as a stopper, the compression ratio in the front, rear, left and right is not more than 20%, so that the shock of transport of the hard disk array device 1 and the storage of the hard disk drive 10 are accommodated. Even if the hard disk drive 10 is greatly displaced by hitting the caddy 20 alone when handling it by itself and giving a large impact acceleration, the destruction of the vibration isolating rubber 32 of each damper 30 can be reliably prevented. In addition, the mechanical reliability of the hard disk array device 1 can be further improved. Further, the stopper can be integrally formed by a simple structure such as changing the position of the vibration damping portion of the vibration isolating rubber 32, and the number of parts is not increased, so that the cost is not increased, and It can be realized without changing the performance.

Although the hard disk array device has been described as a recording / reproducing device according to each of the above embodiments, it is needless to say that the present invention can be applied to other recording / reproducing devices such as an optical disk drive device and a VTR (video tape recorder). However, the recording / reproducing means is not limited to a hard disk drive. Although the screw is used as the fastening means, other fastening means such as a bolt and a nut may be used. Further, in the second embodiment, a part of the vibration damping portion 32c 'of the vertical vibration damping portion is used as a stopper for abutting against the back surface 33a of the mounting plate 33. May be used as a stopper.

Can be improved.

Further, a part of each vibration damping portion on the upper side of the vibration isolating rubber of the damper is disposed so as to be able to abut against each of the mounting plates to form a stopper in the front-rear direction.
