Problems solved by technology

[0020] As described above, in the conventional adjustment method of adjusting the load pressure and the static posture angle θ based on the support portion of the load beam as in the past, even if each magnetic head device is adjusted in the same way, the magnetic head floating by several nm There is also an error in the floating amount

Embodiment

[0129] In the experiment, first, a plurality of magnetic head devices of the same product were prepared. The angle between the highly rigid portion of the load beam and the supporting piece of the elastic member, that is, the static posture angle θ is different for each magnetic head device. Also, the static posture angle θ refers to the posture angle in a state where the slider is not floating on the disk D and no external force acts on it.

[0130] In the experiment, as Figure 19 As shown, it is assumed that in each magnetic head device, the support portion located on the base side of the load beam is fixed with a fixing member, the slider actually faces the disk, and the opposing surface of the slider is kept parallel to the disk. Or in a substantially parallel state, the adjustment member is used to raise it upwards, and the displacement distance is equal to or substantially equal to making the above-mentioned opposing surface and the above-mentioned disk face each other....

Abstract

The present invention provided a method and a device for adjusting a magnetic head device, analyzing a dominant factor influencing a floating amount and using an unconventional adjusting method based on the analysis in a magnetic head floating with a low-floating amount of especially about a few nano-meters. According to this invention, spring pressure of a flexure 24 is properly adjustable without considering various distortion parameters by finding out that flexural pressure has a big influence on a floating amount characteristic and performing adjustment of a static attitude angle [theta] on the basis of a high rigidity part 23d of the load beam 23, and variations of a floating amount in the floating state of the magnetic head can be reduced in such a manner in the magnetic head floating with a low-floating amount about a few nano-meters.

Description

technical field [0001] The present invention relates to a magnetic head device mounted on a hard disk device, etc., and particularly relates to a magnetic head device that floats with a small floating amount of a few nanometers, which analyzes the main factor determining the floating amount and adopts an adjustment method different from the past based on the analysis. A method for adjusting a magnetic head device and an adjusting device for a magnetic head device. Background technique [0002] A magnetic head device mounted on a hard disk device or the like is composed of a slider and a supporting member for supporting it. [0003] The support member is composed of a load beam and elastic members, and the load beam is provided at various positions in the order of a high rigidity part, an elastic deformation part and a support part from the front part side to the base part side. The elastic member is attached to the front portion of the load beam, and a pivot is formed protr...
