Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a magnetic recording / reproducing apparatus cartridge in which a magnetic recording / reproducing apparatus represented by a hard disk device is housed, and an information processing apparatus using the same, and more particularly to a support structure that satisfies both vibration resistance and shock resistance performance.
[0002]
[Prior art]
In recent years, with the increase in capacity and price of hard disk drives being accelerated, hard disk drives (Hard Disk Drive / HDD) are used not only for portable information processing devices represented by notebook PCs, but also for digital TVs and camera recorders. Application to many products is under consideration. The challenge in applying hard disk drives to these products is the development of structures that satisfy both vibration resistance and impact resistance.
[0003]
FIG. 9 is a (a) external perspective view, (b) an internal perspective view, and (c) a longitudinal sectional view showing a configuration of a magnetic recording / reproducing apparatus cartridge in which a hard disk device is housed. In this magnetic recording / reproducing apparatus cartridge 1 (hereinafter referred to as cartridge 1), the storage case 2 is made of, for example, a sheet metal made of SUS303 having a thickness of 0.5 mm, and an upper lid 3 and a lower lid 4 having a U-shaped cross section. An elastic shock absorber 5 made of a thermosetting resin such as silicon or urethane is bonded to the four corners of the inner surface of the upper lid 3 and the lower lid 4 with a double-sided tape. It is stored so as to be sandwiched between the shock absorbers 5.
[0004]
Such a cartridge 1 may be built in a notebook PC or may be used by being mounted in a slot of an information processing device as a removable recording / reproducing device, but is added to the upper lid 3 and the lower lid 4 by dropping or the like. Since the impact is attenuated by the elastic shock absorber 5 and transmitted to the hard disk device 6, it is possible to avoid the destruction of the hard disk device 6. The elastic shock absorber 5 is particularly effective as a vibration-resistant structure because it has a high ability to attenuate high frequencies.
[0005]
[Problems to be solved by the invention]
However, it is difficult to satisfy both the vibration resistance and the shock resistance performance with the elastic shock absorber 5 as described above. Details will be described with reference to FIGS. 10 and 11.
[0006]
FIG. 10 relates to impact resistance performance. The peak value of the impact generated in the hard disk device when the magnetic recording / reproducing apparatus cartridge as described above is dropped is shown as the HDD acceleration (G) in relation to the drop height (m). Curves 91 and 92 are the results when a high hardness material and a low material are used for the elastic shock absorber, respectively. H1 and H2 are calculated by calculating the allowable drop height when each material is used for the same type of hard disk (HDD allowable G value = 500 G). As shown in FIG. 10, the impact resistance performance is improved by using a material having low hardness.
[0007]
FIG. 11 relates to vibration resistance. The result of measuring the limit G value of the hard disk device that can be read and written by applying a sinusoidal acceleration to the magnetic recording / reproducing apparatus cartridge as described above is shown. The horizontal axis represents the excitation frequency (Hz), and the vertical axis represents the vibration resistance impact (G). Lines 93 and 94 are the results when a high hardness material and a low material are used for the elastic shock absorber, respectively. As shown in FIG. 11, the use of a material having high hardness improves the vibration resistance, and the effect is particularly high in the low frequency region.
[0008]
As can be seen from the results of FIGS. 10 and 11, the improvement of the shock resistance performance and the improvement of the vibration resistance performance are in a cut-and-try relationship, and if the impact resistance performance is increased, the vibration resistance performance is sacrificed and conversely the vibration resistance performance. However, it is difficult to achieve the highest performance of both shock resistance and vibration resistance. For this reason, it is necessary to design an elastic shock absorber in consideration of both, and it takes a lot of time for optimization for performance improvement. Therefore, a structure that can satisfy both impact resistance and vibration resistance is still a problem.
[0009]
[Means for Solving the Problems]
SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems, and by using an elastic shock absorber made of a material having low hardness or an elastic shock absorption pack in which an elastic shock absorbing material having low hardness is sealed, the magnetic recording / reproducing apparatus can be operated at a non-operation time.

Thus, the elasticity of the support member is improved by applying a voltage during operation of the apparatus, thereby increasing the compressibility of the elastic shock absorber. In this case, since the elasticity of the support member, that is, the hardness can be adjusted by voltage control, it is possible to realize a structure with higher vibration resistance.
[0014]

[0020]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
(Embodiment 1)
1A is an external perspective view of a magnetic recording / reproducing apparatus cartridge according to Embodiment 1 of the present invention, FIG. 1B is an internal perspective view, FIG. 2C is a longitudinal sectional view, and FIG. The state which attaches | detaches to an apparatus is shown.
[0021]
As shown in FIGS. 1 (a), 1 (b), and 1 (c), the magnetic recording / reproducing apparatus cartridge 1 (hereinafter referred to as cartridge 1) has substantially the same configuration as that of the conventional one described with reference to FIG. The storage case 2 is formed in a box shape with an upper lid 3 and a lower lid 4 having a U-shaped cross section using, for example, a sheet metal made of SUS303 having a thickness of 0.5 mm, and the upper lid 3 and the lower lid 4. The elastic shock absorber 5 in which a thermosetting resin such as silicon or urethane is gelled is bonded to each of the four inner corners with double-sided tape, and the hard disk device 6 is interposed between the upper and lower elastic shock absorbers 5. It is stored so as to be pinched.
[0022]
Although not shown, the hard disk device 6 includes a magnetic recording medium (hard disk), rotating means for rotating the magnetic recording medium, a head for recording and reproducing information on the magnetic recording medium, and control for the rotating means and the head. A circuit or the like is housed inside the box and has a connector portion for electrically connecting to the information processing apparatus.
[0023]
This cartridge 1 is different from the conventional cartridge in that an inclined portion 7 is formed in a direction intersecting with the upper surface and the side surface of the upper lid 3 disposed in the back of the hard disk storage portion of the information processing apparatus. . Further, the upper lid 3 is formed such that the entire thickness of the cartridge 1 is somewhat larger than the height of the hard disk housing portion and that the upper end of the lower lid 4 does not come into contact with the inner surface of the upper lid 3 when not disposed in the hard disk housing portion. , The lower lid 4 and the height of the elastic shock absorber 5 are set. As the elastic shock absorber 5, one having relatively low hardness (for example, KG gel: KG55, Kitagawa Industries Co., Ltd.) is used.
[0024]
For this reason, as shown in FIG. 2 (a), when the cartridge 1 is mounted in the hard disk storage portion 9 opened on the front surface of the main body 8 of the information processing apparatus (here, the desktop PC), as shown in FIG. 2 (b). Thus, by making the inclined part 7 precede, it can be smoothly inserted. Subsequently, as shown in FIG. 3 (c), the upper lid 3 and the lower lid 4 of the cartridge 1 are pressed by the top and bottom surfaces of the hard disk storage section 9, and the cartridge 1 is finally the same as the hard disk storage section 9. Compressed to height. The compression of the cartridge 1 is due to the compression of the elastic shock absorber 14.
[0025]
Therefore, when the cartridge 1 is carried (when not mounted), the elastic shock absorber 5 has a relatively low hardness as described above, so that the impact resistance performance required when carrying the cartridge 1 can be satisfied. On the other hand, when the cartridge 1 is used (attached), the elastic shock absorber 5 is compressed and acts as an apparently high hardness, so that vibration resistance can be satisfied. (See FIGS. 10 and 11 above)
Therefore, it is possible to separate the design of the shock-resistant structure and the vibration-proof structure, improving the design easiness and reducing the development lead time.
(Embodiment 2)
3 is (a) a perspective view of an external application, (b) an internal perspective view, and (c) a longitudinal sectional view of a magnetic recording / reproducing apparatus cartridge according to Embodiment 2 of the present invention.
[0026]
As shown in FIGS. 3A, 3B and 3C, the magnetic recording / reproducing apparatus cartridge 1 (hereinafter referred to as cartridge 1) is substantially the same as that of the first embodiment described above with reference to FIG. Although it has a structure, it is different in that a support member 10 made of a shape memory alloy (for example, Ni—Ti alloy) that contacts the upper lid 3 and the lower lid 4 is arranged. The support member 10 is folded in a zigzag shape so as not to suppress the shape change, and is fixed to the lower surface of the upper lid 3 and the upper surface of the lower lid 4 by spot welding or the like at both ends. The support member 10 is designed to have a length of 30 ° C. or less plus the thickness of the hard disk device 6 and the elastic shock absorber 5 (upper and lower), and to be shortened by 2 to 3 mm when the temperature exceeds 30 ° C. The
[0027]
For this reason, when the cartridge 1 is carried (when not attached), the support member 10 is usually in an atmosphere of 30 ° C. or lower and maintains its original shape and length, so that the upper lid 3 and the lower lid 4 are elastically impacted. The elastic shock absorber 5 that does not compress the absorber 5 and has a relatively low hardness satisfies the impact resistance required when being carried.
[0028]
On the other hand, when the cartridge 1 is used (when it is mounted and the hard disk device 6 is in operation), the heat generated by the hard disk device 6 is transmitted to the support member 18, so that the support member 18 is shortened and the upper lid 3 The lid 4 is pulled in a direction approaching each other, and the upper lid 3 and the lower lid 4 compress the elastic shock absorption resistance 5, whereby the elastic shock absorption resistance 5 acts as an apparently high hardness and satisfies the vibration resistance performance.
[0029]
The support member 10 may be designed not to be shortened as the temperature rises as described above, but to be energized during the operation of the hard disk device 6 and to be shortened thereby. The same effect as above can be obtained.
(Embodiment 3)
4A is a perspective view of an information processing apparatus provided with a magnetic recording / reproducing apparatus cartridge according to Embodiment 3 of the present invention, FIG. 4B is a partially cutaway perspective view, and FIG. It is sectional drawing at the time of use, (b) It is sectional drawing at the time of non-use.
[0030]
As shown in FIGS. 4 (a) and 4 (b), this information processing apparatus is a portable information processing apparatus, and a main body 8 having a hard disk storage section 9 for storing a magnetic recording / reproducing apparatus cartridge 1 (hereinafter, cartridge 1). And an image display device 11 attached to the main body 8.
[0031]
As shown in FIGS. 5A and 5B, the cartridge 1 has substantially the same configuration as that of the first embodiment described above with reference to FIG. The difference is that a protrusion 12 having a height of 2 to 3 mm and a tip width of about 2 mm is provided. At least two protrusions 12 are provided along the direction of attachment / detachment of the cartridge 1 (the direction intersecting with the paper surface) and at intervals along the direction intersecting with the attachment / detachment direction (the left-right direction along the paper surface). ing. In the cartridge 1, the upper end of the lower lid 4 does not come into contact with the inner surface of the upper lid 3 in a state where the protrusion 12 is in contact with the bottom surface of the hard disk housing portion 9 and the upper surface of the upper lid 3 is in contact with the top surface of the hard disk housing portion 9. Thus, the height of the upper lid 3, the lower lid 4, and the elastic shock absorber 5 is set.
[0032]
On the other hand, the lower part of the slide pin 13 that can be moved up and down in the vertical direction intersecting the upper surface of the main body 8 is disposed in the hard disk storage unit 9. The slide pin 13 is urged so that the upper end protrudes from the upper surface of the main body 8 (the urging means is not shown), and the upper end is pressed when the image display device 11 is closed. Descends to a position in contact with the bottom surface of the hard disk storage unit 9.
[0033]
Also attached to the hard disk storage 9 is a slider 14 that slides along the bottom surface of the hard disk storage 9 as the slide pin 13 is moved in and out. The slider 14 has a sheet metal structure made of SUS304 or the like and having a thickness of about 0.5 mm. At the stopper 15 at one end, the slider 14 is formed on the bottom surface of the end of the hard disk storage 9 that is away from the slide pin 13 (the left end in this figure). It is fixed with screws. Further, a zigzag spring portion 16 is provided in the vicinity of the stopper 15, and the other end portion is bent so as to be inclined at about 45 to 60 degrees with respect to the bottom surface of the hard disk storage portion 9. It has an inclined portion 17 that is pressed against the slide pin 13 with (restoring force from the compressed state). Projections 18 having the same shape as the projections 12 of the lower lid 4 are formed at the same pitch as the projections 12 at predetermined positions on the upper surface of the slider 14.
[0034]
In such a portable information processing device, when the image display device 11 is open (the information processing device is being used and the hard disk device 6 is also in a driving state), the slide pin 13 is slid upward, A gap is formed between the lower end and the bottom surface of the hard disk storage unit 9. Accordingly, the slider 14 is pushed toward the slide pin 13 by the biasing force of the spring portion 16, and the inclined portion 17 is in pressure contact with the lower end of the slide pin 13, and the protrusion 18 on the upper surface of the slider 14 is the bottom surface of the lower lid 4. The tip of each of the projections 12 is in contact with each other. For this reason, the lower lid 4 is lifted 2 mm upward by the height of the protrusion 18, and the cartridge 1 is compressed in the thickness direction. This is due to compression of the elastic shock absorber 5, and the elastic shock absorber 5 is apparently a material having high hardness. Therefore, the vibration resistance required when using the hard disk device 6 can be satisfied.
[0035]
On the other hand, when the image display device 11 is closed (the information processing device is stopped and the hard disk device 6 is also stopped), the slide pin 13 is pushed down by the image display device 11, and the lower end thereof is an inclined portion. 17 is pressed downward, whereby the slider 14 is slid leftward by the compression force of the spring portion 16. Along with this, the protrusion 18 on the upper surface of the slider 14 returns from the bottom of the protrusion 12 on the bottom surface of the lower lid 4 to the meshing position, and the lower lid 4 returns to the original position. As a result, the compression of the elastic shock absorber 5 is released, and the elastic shock absorber 5 acts as a material with low original hardness. Therefore, it is possible to satisfy the impact resistance required when being carried.
(Embodiment 4)
FIG. 6 shows a magnetic recording / reproducing apparatus cartridge according to Embodiment 4 of the present invention and a hard disk storage section of an information processing apparatus in which the cartridge is installed.
[0036]
As shown in FIG. 6, this magnetic recording / reproducing apparatus cartridge 1 (hereinafter referred to as cartridge 1) has a gel (for example, KG gel: Kitagawa Kogyo Co., Ltd.) formed in a bag 19 made of a soft material such as nylon or rubber. The hard disk device 6 is buffered and held in an elastic shock absorbing pack 21 in which a viscous fluid 20 is sealed, and a pressure adjusting member 22 for controlling the internal pressure of the elastic shock absorbing pack 21 is provided in the hard disk housing 9. It has been. The elastic shock absorbing pack 21 corresponds to the elastic shock absorber described in claim 6.
[0037]
The elastic shock absorbing pack 21 includes a substantially rectangular parallelepiped casing portion 21a that covers the hard disk device 6 from the lower surface to the peripheral edge of the upper surface, and a pressure adjusting portion 21b that communicates with the casing portion 21a at the lower portion. The piston 23 that constitutes a part of the pressure adjusting member 22 is coupled to the upper part.
[0038]
The upper end portion of the piston 23 is pivotally supported by one end of a guide pin 25 that is pivotally supported at the central portion of the column 24 of the hard disk storage portion 9, and the other end of the guide pin 25 is the lower end of the slide pin 13 described above. And the other end of the compression spring 26 having one end coupled to the bottom surface of the hard disk storage unit 9 is coupled. As a result, when the slide pin 13 is raised, the piston 23 is lowered to press the pressure adjusting portion 21b to increase the internal pressure of the elastic shock absorbing pack 21, and conversely, when the slide pin 13 is lowered, the elastic shock absorbing pack 21 is pressed. The internal pressure is reduced.
[0039]
In such a portable information processing device, when the image display device 11 is opened (the information processing device is being used and the hard disk device 6 is also in a driving state), the slide pin 13 is moved by the restoring force of the compression spring 26. The piston 23 is lowered by sliding upward, and the elastic shock absorbing pack 21 whose internal pressure is increased by the piston 23 is apparently a material having high hardness. Therefore, the vibration resistance required when using the hard disk device 6 can be satisfied.
[0040]
On the other hand, when the image display device 11 is closed (the information processing device is stopped and the hard disk device 6 is also stopped), the slide pin 13 is pushed down by the image display device 11, thereby causing the piston 23 to move. As the pressure rises, the internal pressure of the elastic shock absorbing pack 21 decreases, and the elastic shock absorbing pack 21 acts as a material having low hardness. Therefore, it is possible to satisfy the impact resistance required when being carried.
[0041]
In the case of this elastic shock absorbing pack 21, the rigidity (hardness) of the side portion of the hard disk device 6 can be changed, so that it is easy to deal with impact and vibration from the lateral direction.
The cartridge 1 is installed in the hard disk storage unit 9, but can be taken out from the hard disk storage unit 9 by releasing the connection between the upper end of the piston 23 and the guide pin 25.
(Embodiment 5)
7A is an external perspective view of a magnetic recording / reproducing apparatus cartridge according to Embodiment 5 of the present invention, FIG. 7B is a partial perspective view thereof, and FIGS. 8A, 8B, 8C, and 8D are shown. ) Shows an operation when the magnetic recording / reproducing apparatus cartridge is detached from the information processing apparatus.
[0042]
As shown in FIG. 7 (a), the magnetic recording / reproducing apparatus cartridge 1 (hereinafter referred to as cartridge 1) has substantially the same configuration as that of the first embodiment described above with reference to FIG. However, it is different in that the upper lid 3 has a ventilation structure.
[0043]
As shown in FIG. 7 (b), the upper lid 3 is formed with a plurality of slits 27 (width 2 to 3 mm) in a direction intersecting with the attaching / detaching direction of the cartridge 1. A square hole 28 is formed at a position on the outside and opposite to the inclined portion 7. A pair of guide rails 29 movably holding the slit plate 30 are provided on the inner surface of the upper lid 3 along the direction of attaching and detaching the cartridge 1 with a width 0.5 to 1 mm longer than the lateral width of the slit plate 30. .
[0044]
As shown in FIG. 7 (c), slits 30 having the same width and the same length as the slits 27 of the upper lid 3 are formed in the slit plate 30 in the same direction, the same pitch, and the same number as the slits 27. A notch 32 is formed in the square hole 28 of the upper lid 3 and slides in the square hole 28 as the slit plate 30 moves.
[0045]
As shown in FIG. 8A, the slit 31 and the notch 32 are not overlapped with the slit 27 of the upper lid 3 in the state where the notch 32 is located in the center of the square hole 28. ), The slit 31 is designed to overlap the slit 27 of the upper lid 3 in a state where the notch 32 is moved to an end portion (end portion far from the inclined portion 7) in the square hole 28.
[0046]
As shown in FIGS. 8 (c) and 8 (d), a notch 32 protruding from the square hole 28 of the upper lid 3 can be locked to the opening end of the hard disk storage portion 9 of the information processing apparatus (for example, portable information processing apparatus). A concave portion 9a is formed.
[0047]
For this reason, when the cartridge 1 is carried (when the hard disk device is not operating), the notch 32 is positioned at the center of the square hole 28 as shown in FIG. 31 and the slit 27 of the upper lid 3 are in a positional relationship such that they do not overlap with each other, and intrusion of water droplets and dust from the slit 27 is avoided.
[0048]
On the other hand, as shown in FIGS. 8 (c) and 8 (d), when the cartridge 1 is inserted and installed in the hard disk storage unit 9, the notch 32 is caught in the recess 9a, and as shown in FIG. 8 (b). The slit plate 30 moves until the notch 32 hits the end in the square hole 28, and the slit 31 of the slit plate 30 overlaps the slit 27 of the upper lid 3. Therefore, the heat generated in the hard disk device 6 is released to the outside of the cartridge 1 through the slits 27 and 31, and the temperature rise of the hard disk device 6 is avoided.
[0049]
It is the same as the cartridge of the first embodiment that both vibration resistance and shock resistance can be satisfied.
Although not shown, an urging means for urging the slit plate 30 is provided so that the notch 32 is positioned at the center of the square hole 28 when the cartridge 1 is not mounted, and the cartridge 1 is stored in the hard disk. When taken out from the section 9, the slit plate 30 automatically moves so that the slit 31 of the slit plate 30 and the slit 27 of the upper lid 3 do not overlap.
[0050]
If the height of the notch 32 is set to be equal to or less than the thickness of the upper lid 3 and the slit plate 30 is manually moved by the notch 32 and can be held at the position after the movement, the recess 9a as described above is provided. The cartridge 1 can also be used in a hard disk storage 9 that is not present.
[0051]
The ventilation structure of the cartridge 1 may be applied to the cartridge of the second embodiment or the third embodiment.
Furthermore, the vibration proof, shock proof structure, and ventilation structure of the first to fifth embodiments can be applied to the optical disc apparatus.
[0052]
