Problems solved by technology

Since there is no proper grounding structure on the second insulating layer 152, static charges cannot be released before the magnetic head 103 is assembled to other components
In this way, in the process of assembling the magnetic head 103 to other parts, the above-mentioned wire layer 153 is easy to generate an electrostatic discharge phenomenon through contact with the low-potential outside world (such as the operator's hand, clamps, etc.), and the current passes through the contact with the low-potential outside world (such as the operator's hand, clamps, etc.) The reading and writing components connected by the wire layer, as a result, the reading and writing components of the magnetic head are burned

Embodiment Construction

[0027] Embodiments of the present invention will now be described with reference to the drawings. Figure 2a-2b A flexible mounting slider (Flexible Mounting Slider, FMS) with an electrostatic protection structure according to an embodiment of the present invention is shown. As shown in the figure, the flexible assembly head 203 includes a head body 255 , an ESD protection structure 291 disposed on the head body 255 , and a wire layer 253 inside the ESD protection structure 291 .

[0028]The magnetic head body 255 has an air bearing surface (air bearing surface, ABS) 280 for forming aerodynamic contact with the magnetic disk (such as the magnetic disk 201 shown in FIG. 4 ) and a magnetic head back surface 281 opposite to the air bearing surface 280. . The magnetic head back surface 281 is used to install the magnetic head body 255 to the suspension (such as image 3 Shown cantilever 251). The head body 255 also has a trailing edge 284 connected to the air bearing surface 28...

Abstract

A flexible assembling magnetic head with electrostatic protection structure, includes a magnetic head body which is arranged with an air load-bearing surface, a magnetic head reverse facing to the air load-bearing as well as a cauda edge connected to the air load-bearing surface and the magnetic head reverse, a pair of magnetic head contacts are formed on the cauda edge; an electrostatic protection structure settong on the magnetic head reverse comprises an insulating disc setting on the magnetic head reverse, an electrostatic resistance disc setting on the insulating disc and composed of the insulating layer as well as an electrostatic resistance layer, and an earthing element contacting electrically to the electrostatic resistance of the electrostatic resistance disc as well as the magnetic head reverse; as well as a wire layer locating between the insulating disc and the insulating layer of the electrostatic resistance disc, and contacting electrically to the magnetic head contact of the magnetic head body. The present invention discloses a magnetic head disc-folding combination containing the flexible assembling magnetic as well as a magnetic disk drive unit.

Description

technical field [0001] The present invention relates to an information recording disk drive unit, and more particularly to a flexible assembled magnetic head with an electrostatic protection structure, a magnetic head flap assembly and a magnetic disk drive unit, so as to avoid or weaken the impact of static electricity on the magnetic head during the assembly process of the magnetic disk drive unit, etc. Destructive effects of read and write components. Background technique [0002] A common information storage device is a magnetic disk drive unit, which uses magnetic media to store data and selectively reads data from the magnetic media or writes data to the magnetic on the medium. [0003] 1a-1b illustrate a conventional disk drive unit 200 . As shown, a magnetic disk 101 is mounted on and rotated by a spindle motor 102 . The HGA 100 is connected to the voice coil motor arm 104 . The HGA 100 includes a suspension 111 and a magnetic head 103 installed at the end of the...
