Problems solved by technology

It has been pointed out that one of the reasons is that the shape of the grinding surface of the strip actually needs to be similar to a high-order curve of more than 6 degrees in the length direction of the strip, and the traditional support method for the strip can only imitate at most Quadruple curve, which reduces yield (refer to Patent Document 3)

Abstract

The invention discloses a milling holder which comprises: a holding part which makes the milled side of the milling object to the milling side of the miller, a body which fixes the milling holder on the miller, a plurality of load addition parts which are arranged on the length direction and at least receive the sequenced direction load of the milling side, a plurality of connecting parts which connect the holding part and the body part on the length direction and a plurality of lug parts which connect each load blending part and the holding part. It arranges at least one lug part between the adjacent connecting parts and the outer side of the two ends of the connecting part along the length direction.

Description

technical field [0001] The present invention relates to a kind of magnetic head manufacturing method with thin-film magnetic head, especially about the jig for polishing the magnetic head, the grinding device and the grinding flatness along the longitudinal direction of the elongated bar (bar) formed by a plurality of magnetic heads. method. Background technique [0002] Disk drives (disk drives), which are high-speed, large-capacity, high-reliability, and low-cost recording media, are widely used for recording digital information. After years of technological development, the recording density of magnetic disk drives has exceeded 100 Gbits / square inch. The magnetic disk drive is provided with a magnetic head (hereinafter referred to as a magnetic head) including a thin-film magnetic head for recording and reproducing information on a recording medium. The surface of the magnetic head facing the recording medium is called the air bearing surface (ABS). [0003] In an MR e...
