Abstract

PURPOSE:To eliminate a seek error due to a dislocation between a supporting spring and a negative pressure slider, and to improve reliability for a magnetic disk device remarkably by constituting a device so that the negative pressure slider is supported with a needle arranged on the supporting spring. CONSTITUTION:The supporting mechanism of the negative pressure slider is constituted providing with a negative pressure slider 1 equipped with a cone- shaped recessed part 2 at the center part of a back plane, and a supporting spring 5 equipped with a needle 7 engaged in the recessed part 2, and the negative pressure slider 1 is constituted so as to be coupled with the supporting spring 5 through the needle 7 inserted to the recessed part 2 of cone shape. Since the negative pressure slider 1 and the supporting spring 5 are coupled with each other at one point, and so-called 'sliding phenomenon' is not generated, the seek error is not generated.

Description

[Detailed Description of the Invention] [Summary] The negative pressure slider support mechanism of the present invention has a configuration in which the tip of a needle disposed on a support spring is inserted into a recess provided on the back surface of the negative pressure slider. It has become.

Therefore, the shaking (pitching) and rolling of the negative pressure slider in the track direction during seek are reduced, and the operation of the magnetic disk device is stabilized.

[Industrial application field]

The present invention relates to an improvement in a support mechanism for a negative pressure slider installed in a magnetic disk drive.

[Jurai technology]

FIG. 2 is a sectional side view of a main part showing a conventional slider support mechanism.

As shown in the figure, the slider support mechanism connects a support spring 5 disposed on a spacer 9, a negative pressure slider 1 equipped with a pivot 4 on the back surface, and the slider 1 and the support spring 5. The negative pressure slider 1 and the support spring 5 are constructed by a gimbal 6, and the negative pressure slider 1 and the support spring 5 are moved relative to each other in the in-plane direction by the frictional force generated by the pressing force W of the support spring 5 acting on the contact point P between the pivot 4 and the support spring 5. (Since the gimbal 6 is formed to be soft so as not to restrict the movement of the negative pressure slider 1, the force for correcting the relative positional deviation in the in-plane direction between the support spring 5 and the negative pressure slider 1 is (I don't expect much.)

At the time of seek, the support spring 5 moves in the direction of arrow A or in the direction of 8" to move the negative pressure slider 1 to a desired trunk on the disk medium 8 (the seek acceleration at this time is about 50 G). ). Therefore, when seeking, the quality ff10.04 g slider 1 to 2
A force of g will be added.

[Problem that the invention seeks to solve]

However, in the conventional slider support mechanism described above, the pressing force W is often set to an extremely low value of 0 to 5 g as a measure to reduce wear when starting and stopping the negative pressure slider. The frictional force acting between the pivot 4 and the support spring 5 is 2g, which is the minimum value necessary to "connect without positional deviation" between the two (the friction coefficient between the pivot 4 and the support spring 5 is approximately 0.3, and the frictional force is at most 1.5
Therefore, a problem arises in that a "pass slipping phenomenon" occurs at the pivot contact point P, making it impossible to perform a normal sorter operation.

[Means for solving problems]

As shown in the embodiment of FIG.
A needle 7 is arranged on a support spring 5 that forms a conical depression 2 in the center of the back surface of the needle and supports a negative pressure slider into the depression.
By engaging the tips of the negative pressure slider 1 and the support spring 5, the negative pressure slider 1 and the support spring 5 are connected to each other without slipping.

[Effect]

In this structure, the conical recess 2 on the back surface of the negative pressure slider and the needle 7 attached to the support spring 5 engage with each other to prevent positional deviation 2 between the negative pressure slider 1 and the support spring 5 during seek. That is, the "slip phenomenon" is eliminated, and the reliability of the seek operation is improved.

〔Example〕

The present invention will be described in detail below based on embodiments shown in the drawings.

FIG. 1 is a side sectional view of the main part showing an embodiment of the present invention.
The same parts as in FIG. 2 are given the same reference numerals.

As shown in the embodiment of FIG. 1, the negative pressure slider support mechanism of the present invention includes a negative pressure slider 1 having a conical recess 2 at the center of the back surface, and a needle 7 inserted into the recess 2. The negative pressure slider 1 is connected to the support spring 5 through a needle 7 inserted into a conical recess 2.

Therefore, in the case of the magnetic disk drive of the present invention, the negative pressure slider 1 and the support spring 5 are connected to each other at one point, so that a so-called "sliding phenomenon" does not occur, so that no seek error occurs.

〔Effect of the invention〕

As explained above, the present invention has a structure in which the negative pressure slider is supported by the needle disposed on the support spring.
Seek errors caused by misalignment between the support spring and the negative pressure slider are eliminated, and the reliability of the magnetic disk drive is significantly improved.

Furthermore, since the present invention has a structure that supports the vicinity of the center of gravity of the slider, there is less rolling during seek.
