AI Technical Summary

Problems solved by technology

Adhesives also have less adhesion and as a result, durability becomes difficult to improve
Conversely, if the anisotropic conductive adhesive contains less conductive material, the conductivity of the adhesive is reduced (resistance is increased) and thus sufficient continuity between the head slider and the suspension cannot be achieved

Embodiment Construction

[0029] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] [Magnetic head assembly according to an embodiment of the present invention]

[0031] Figure 5 Shown is the external structure of a magnetic disk device using the magnetic head assembly according to an embodiment of the present invention. This magnetic disk apparatus includes a magnetic head slider (hereinafter also referred to as a magnetic head or head) 11 having a substrate and a magnetic head core portion formed on the substrate, and a magnetic disk (hereinafter also referred to as a disk) 110 as a recording medium. The magnetic disk 110 is rotated by a spindle motor 111 . The magnetic head slider 11 is supported by the tip of the suspension 12 at one end. The other end of the suspension 12 is connected to the driving arm 131 . The magnetic head slider 11 is disposed facing the surface of the magnetic disk 110 . The drive arm 131 is made...

Abstract

To simplify manufacturing processes, to improve workability and durability and to prevent the occurrence of a dielelctric breakdown of a head element in a magnetic disk device.A gimbal section, which supports a magnetic head slider, makes up a portion of the flexure in the suspension of a magnetic head device. Insulating spacers are formed on the section and an electrically conductive pattern is formed to electrically connect the top surfaces of the spacers and the surface of the section. The slider is adhered by adhesive on the section and fixed. Regardless of the conductivity of the adhesive, a grounding electrode of a back surface of the slider is surely grounded and connected through the pattern and the flexure.

Description

technical field [0001] The present invention relates to a slider suspension and a head assembly for mounting at least a magnetic recording head element or a magnetic reproducing head element in an information recording and reproducing apparatus such as a magnetic disk apparatus or a magneto-optical disk apparatus, and a method of manufacturing the same. The head slider, the head assembly has a slider suspension and a head slider mounted on the slider suspension. Background technique [0002] Generally, in a head assembly structure, a head slider having a head element is supported by a slider suspension (hereinafter referred to as a suspension). Information is reproduced / recorded from / on a recording medium such as a magnetic disk when the head slider is lifted by a suspension at a fixed distance from the surface of the magnetic recording medium. [0003] Such a suspension type head assembly has hitherto been assembled in such a manner that the head slider is attached to the ...
