Embodiment Construction
[0089] Several embodiments of the present invention are now described with reference to the drawings, in which like reference numerals represent like elements. Figures 5a-5b A magnetic head separation auxiliary device 500 for separating a magnetic head 501 from a jig 510 according to the first embodiment of the present invention is shown. The magnetic head separation auxiliary device 500 includes a jig support plate 520 for fixing the jig 510 , a separation bracket 530 , and a separation bracket support plate 540 for fixing the separation bracket 530 .
[0090] First, the formation of the magnetic head 501 will be briefly described. As we all know, the magnetic head is formed on the row bar. For details, please refer to Figure 6a and Figure 6b A group of elongated strips 505 are bonded side by side on the jig 510 along the Y direction, so each elongated strip 505 extends along the X direction, and then on the jig 510 along the Y direction with an appropriate gap. The gro...

The invention discloses a magnetic head separation auxiliary device for separating a magnetic head from a tool and containing the magnetic head, which comprises a separation bracket, a plurality of magnetic head containing pits in matrix arrangement are formed on the top surface of the separation bracket, and the adjacent magnetic head containing pits on each column are separated by partitions, causing the partitions and the magnetic head containing pits to be in one-to-one correspondence, wherein one side of each partition forming the inner wall of the corresponding magnetic head containing pit is an inclined surface, causing the partition to be in a structure with a thin upper part and a thick lower part, the inclined surfaces of the partitions on the same column all incline towards the same side, and the planes where the inclined surfaces of the partitions on two adjacent columns are positioned are mutually crossed, causing the two adjacent partitions on each line to form into the side walls of the two corresponding magnetic head containing pits of the two adjacent partitions. The invention also discloses a method for manufacturing magnetic heads by using the magnetic head separation auxiliary device.
Description
technical field [0001] The present invention relates to a method and device for manufacturing an information recording disk drive unit, in particular to a method and device for manufacturing a magnetic head in an information recording disk drive unit, and more particularly to a method for separating the magnetic head from a jig (exposure jig) Auxiliary device and method for manufacturing a magnetic head using the device. Background technique [0002] A common type of information storage device is a magnetic disk drive system that uses magnetic media to store data and to selectively read data from the magnetic media using a magnetic head with a read-write sensor element movably positioned over the magnetic media data or write data on magnetic media. [0003] The magnetic head described above is formed by performing a series of processes on a wafer used to manufacture the magnetic head. Firstly, after the wafer is ground, cleaned, deposited and etched, the processed wafer is...
