Abstract

PURPOSE:To prevent failure by providing buffer members along the moving route of a head and pressing the head to the buffer members when impact is applied on a recording medium in the direction perpendicular thereto. CONSTITUTION:A pair of the upper and lower buffer members 3 are provided along the moving route in the arrow (c) direction of the head 4 with a pair of upper and lower sliders in the position near the head 4 opposite from a head disk 5. A pair of the buffer members 13 are mounted by adhesion to a housing body 6 which is the inside surface of a housing 8 and a housing cover 7. The head 4 is presed to the buffer members 13 when large impact is applied on the housing 8 in the direction prpendicular to the hard disk 5. The impact energy is thereby absorbed and the impact is relieved. The failure of the head 4 and a head support 2 is prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a disk device that is most suitable for storing a disk-shaped recording medium such as an l' disk.

SUMMARY OF THE INVENTION The present invention provides a disk device for recording and reproducing information on a disk-shaped recording medium using a head attached to the tip of a head moving member. By providing this material, damage to the hesode due to impact can be prevented.

[Jubei's prostitution techniques]

For example, as seen in Japanese Unexamined Patent Application Publication No. 55-22296, in a hard disk drive developed by the United States for recording and reproducing hard disks, as shown in FIG. First support 2 supported by a spring
Attach the second support 3, which is made up of a leaf spring that is thinner and softer than the leaf spring that constitutes the first support 2, to the tip of the first support 2, and A head 4 with a slider is bonded to the movable part.

First, the hard disk 5, which is a disk-shaped recording medium pot,
The head 4 with the slider is rotated by the first and second supports 2, and the head 4 with the slider is rotated with a micrometer against the elasticity of the filter. height,
The head moving member 1 moves the sliders 1 and 1 and the head 4 almost in the radial direction of the hard disk 5 (to make them hyperactive (scan)).
·line'. loII, second support 3 fd no=1・l
- Control the attitude of the head 4 with the slider when it is floated.

[Issues that Brother Akira would like to solve]

However, with conventional American hard disk devices, for example,
An arrow that is perpendicular to the do disk 5; The second support 5-1, which is the head holding part, is swung largely in the direction of the stamp a.
('The one with the slider and the one with the slider 4 are easy to damage.) In particular, in the case of a lug tong specification (the above-mentioned impact atmosphere may exceed 200 GY, as mentioned above), damage to the head support section becomes a problem.

Akiichi Kimi, opposition! Therefore, the objective is to provide a 17-inch disk device that can prevent damage to the head support section X'.

[Means to solve fewer problems]

Regarding the above [1], secondly, the disc of the present invention
Place it on the tip of the moving member.
'h At the position opposite to the disk-shaped recording medium of the head,
The movement path of the doki head is K, and the buffer member Z is provided with two parts.

``Function'' According to the above, in a disk device, when a strong impact is applied to the disk-shaped recording medium in a direction perpendicular to it, the head comes into contact with the buffer member K and the impact is absorbed. Since the pressure is relaxed, damage to the head support portion and the head can be prevented.

[Embodiments] Hereinafter, each embodiment of the present invention applied to a hard disk drive will be described with reference to FIGS. 1 and 2.

Ok, the same configuration as the conventional example shown in Figure 5 has the same structure.
As is well known, a hard disk drive has a seal and a redundant explanation. g , - Housing body 6 housing force bar 7; il-”

Then, high speed 1111 in the direction of arrow b of hard disk 1
Due to the air flow generated by the rotation, the head 4 with the upper and lower sliders is moved against the first and second supports 2 and ? 1) Move the head 4 with a pair of upper and lower sliders in the direction of the arrow G, which is approximately the direction of the hard disk 5, and move it to the moving member 1. : Configure both sides of the bottom for recording and playback (5).

Then, the five hard disks of the pair of slide die heads 4 are located on the opposite side of the slide die.
A pair of upper and lower buffer members 15 are provided to slide along the movement path of the head 4 in the direction of arrow I: i1c. It is preferable that the cushioning members 13i and 13i are made of an elastic material that has higher shock absorbing properties than silicone rubber or foamed elastic material and is less likely to generate dust.

The pair of loose members 13 are attached to the circular housing body 6 and the housing force bar 7 of the l1 housing 8 by adhesive or the like.

In addition, 11 circulation filters 14 are installed on the outer periphery of the hard disk 5 in the housing 8 at a position close to the buffer phase 15.

8 J6, due to the high speed rotation of the hard disk 5, the airflow is caused by a pair of upper and lower slitters, A pair of shock absorbing members 1 and 1./r cause the force to smoothly flow in the direction of the inner periphery of the hard disk 5 or the inner periphery of the hard disk 5. Because of this, the dust contained in the airflow is filtered through the circulation filter.
