Magnetic head folding-piece combination and its magnetic disc drive unit assembling method

Abstract

The method includes following steps: (1) providing a magnetic head and suspension in use for bearing the magnetic head; (2) placing glue with thermosetting property between magnetic head and suspension; (3) using infrared heat source to irradiate the magnetic head so that the glue is solidified by heat energy transferred from the magnetic head. Thus, the magnetic head is fixed on the suspension. Using infrared heat source to solidify glue, the method possesses features of shorter solidified time, easy of controlling temperature, high safety, small volume, and low cost. The invention also includes method of assembling disk drive system of containing the composition of folded piece of magnetic head.

Description

technical field [0001] The invention relates to an assembly method of a disk drive unit, in particular to a method for assembling a magnetic head to a magnetic head gimbal assembly. Background technique [0002] A magnetic disk drive is a common information storage device, which includes a magnetic medium for storing data and a movable magnetic head placed on the magnetic medium for selectively reading or writing data from the magnetic medium. [0003] Fig. 1 is a structural diagram of a typical disk drive unit, as shown in the figure (for the sake of clarity, the upper cover of the disk drive unit is not shown), the disk drive unit 100 mainly includes a group of concentric disks 10, the The disk 10 rotates around a spindle motor 12 . The permanent magnet 22 is coupled to a voice coil 24 . The voice coil 24 is connected to a voice coil motor 26 , and the other end of the voice coil motor 26 is connected to a set of driving arms 27 . The permanent magnet 22 , the voice coil ...

Problems solved by technology

However, due to the strong directionality of the laser, under normal circumstances, when each beam of laser cures the magnetic head tab combination, the positioning accuracy of the magnetic head tab relative to the laser source is very high, and a slight displacement will lead to a large curing temperature. The change directly affects the curing effect; secondly, due to the high energy of the laser, the temperature can be raised to a large value in just a few tens of seconds, so the temperature is not easy to control, which leads to the quality of the magnetic head assembly. Stable; in addition, due to the high cost of the laser generator, the cost of using this laser treatment method is very high; finally, due to the high intensity and energy of the laser, it constitutes a threat to the safety of operators
