BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a head slider surface cleaning device for cleaning the slider surface of a Winchester type head provided in a magnetic disk medium inspection apparatus.

0002

2. Description of the Related Art Magnetic disk medium testing devices such as certifiers and glide testers that test magnetic disk media individually are equipped with Winchester-type heads.

This Winchester type head is supported by a very thin fork-shaped leaf spring at the tip of the head arm. When the slider surface on the lower surface of the head comes into contact with the rotating single magnetic disk medium surface,
The inspection device inspects the magnetic disk medium.

By the way, when the head slider surface is in contact with a rotating magnetic disk medium, dust adhering to the magnetic disk medium becomes attached to the head slider surface. This dust gradually accumulates on the end of the head slider surface. As described above, if dust accumulates on the head slider surface, the magnetic disk medium cannot be inspected with high performance, so the head slider surface must be cleaned regularly to remove the accumulated dust. Must not be.

Conventionally, cleaning of the head slider surface has been carried out by the inspector who inspects the magnetic disk medium using a cotton swab or the like.

[0006]

[Problems to be Solved by the Invention] However, in conventional cleaning performed by an inspector using a cotton swab or the like, the inspector applies more force than necessary to the head slider surface, which causes the plate spring supporting the head to Not only may the elastic function of the head slider be impaired, but also a cotton swab or the like may be caught on the end of the head slider surface, deforming the leaf spring.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a head slider surface cleaning device that can clean the head slider surface without interfering with the elastic function of the leaf spring supporting the head or deforming the leaf spring. It is about providing.

[0008]

[Means for Solving the Problems] In order to achieve the above object, the present invention provides, for example, with reference to FIGS. 1 and 2, a head slider surface (17) on a support base (1) in a sliding direction A cleaning member (2) on a flat band plate that can reciprocate in parallel with the head slider surface (17) and has a cleaning cloth (4) on the upper surface that contacts the head slider surface (17). and a cleaning member reciprocating means (3) for reciprocating the cleaning member (2) at a predetermined speed.

[0009]

[Operation] According to the above structure, the head slider surface (17) is attached to the cleaning cloth (4) on the upper surface of the cleaning member (2).
) are in contact with each other, the cleaning member (2) moves the head slider surface (17) in the sliding direction of the head slider surface (17) by the cleaning member reciprocating means (3).
), the head slider surface (17)
Clean.

Therefore, when the cleaning member (2) cleans the head slider surface (17) by its reciprocating motion, the cleaning member (2) cleans the head slider surface (17).
17), and the cleaning member (2) is not caught on the end of the head slider surface (17).

As a result, the elastic function of the leaf spring (15) that supports the head (16) is not impaired, and the leaf spring (15)
5) The head slider surface (17) can be cleaned without deforming the head slider surface (17).

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

This head slider surface cleaning device includes a support base 1 which is the main body of the device, a cleaning member 2 that reciprocates on the support base 1, and a cleaning member reciprocating mechanism 3 for reciprocating the cleaning member 2. It is composed of:

The cleaning member 2 has a flat band shape, and a cleaning cloth 4 is attached to the upper and lower surfaces thereof.

The cleaning member reciprocating mechanism 3 includes a slider 6 that is fitted into a guide groove (dovetail groove) 5 formed on the upper surface of the support base 1 and slides along the guide groove 5 on the upper surface of the support base 1; A deformed cam 7 for reciprocating the slider 6, a motor 8 for rotating the deformed cam 7 at a low speed, and a motor 8 for rotating the deformed cam 7 at a low speed so that the end surface 9 of the slider 6 is always in contact with the cam surface 10 of the deformed cam 7. A slider biasing spring (
coil spring) 11.

The motor 8 is installed on one side of the support base 1,
The deformable cam 7 is attached to the rotating shaft 12 of the motor 8, and the slider biasing spring 11 is interposed between the support base 1 and the slider 6.

The cleaning member 2 is removably attached to the slider 6 of the cleaning member reciprocating mechanism 3 with screws 13. When the slider 6 reciprocates at a low speed on the upper surface of the support base 1 due to the rotation of the deformable cam 7, the slider 6 reciprocates together with this. In this case, the cleaning member 2 is attached to the head slider surface 17 of the head 16 supported by a very thin fork-shaped leaf spring 15 at the tip of the arm 14 in the sliding direction (in the direction of arrows a and b). It reciprocates in parallel.

When cleaning the head slider surface 17 using the present head slider surface cleaning device, first, the support stand 1 is installed in such a state that the cleaning member 2 reciprocates along the sliding direction of the head slider surface 17. Next, the head slider surface 17 is cleaned by the cleaning member 2.
(cleaning cloth 4). When the motor 8 is rotated in this state, the deformable cam 7 rotates in the direction of the arrow, thereby causing the slider 6 biased by the slider biasing spring 11 to reciprocate in the directions of arrows a and b. Therefore, the cleaning member 2 reciprocates in the sliding direction of the head slider surface 17 parallel to the head slider surface 17, and the cleaning cloth 4 cleans the head slider surface 17.

The cleaning member reciprocating mechanism 3 of this embodiment employs a method in which the slider 6 is reciprocated by a deformable cam 7 and a slider biasing spring 11.
It is also possible to use a method in which the slider 6 is moved back and forth using a link or the like.

[0021]

As explained above, the head slider surface cleaning device of the present invention cleans the head using a flat strip-shaped cleaning member that reciprocates in the sliding direction of the head slider surface parallel to the head slide surface. Since the slider surface is cleaned, the head slider surface can be cleaned without impairing the elastic function of the leaf spring supporting the head or deforming the leaf spring.
