Embodiment Construction

[0051] Now, a method for deforming a ceramic rod according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that since the object to be actually ground is not limited to the ceramic rod, the ceramic rod will be referred to as "the object to be ground" hereinafter. figure 1 An example of deforming a ground object using this method is shown in . A plurality of elements 170 are formed on the surface of the ground side 92 a of the object 92 to be ground, and the opposite surface thereof is mounted to the side longitudinal frame 94 . Although the exposure boundary 172 formed by each exposure process in the decomposed exposure process when forming the element cannot actually be observed as a distinct boundary, the exposure boundary is indicated by a dotted line in this example for convenience.

[0052] As mentioned above, various factors can produce errors in the positions where elements are formed...

Abstract

When electric elements are formed on a ceramic bar or the like, the positional displacement of the respective elements occurs due to a division exposing process or the like. An object of the present invention is to provide a device and a method which unify the non-polished portion of the respective elements by conducting polishing while a complicated deformation or the like is given to the ceramic bar. To achieve this object, the ceramic bar or like is held by using a jig, and a plurality of loads are applied to portions of the jig where the ceramic bar or the like is held, to thereby deform the ceramic bar or the like and polish the element in that state. In this situation the load applied points are disposed so as to avoid the boundaries of the division exposure.

Description

technical field [0001] The invention relates to a magnetic head grinding device for grinding an object to be ground, on which a plurality of magnetic heads are arranged, the invention also relates to a method for grinding a magnetic head, more specifically, the The invention relates to a device for correcting the curvature of a workpiece or object being ground during grinding. Background technique [0002] A thin film magnetic head used in a magnetic disk device or the like is manufactured from a member obtained by processing a rod-shaped ceramic (hereinafter referred to as "ceramic rod"). A large number of element parts formed of magnetic head films and the like forming an inductive magnetic conversion element or a magnetoresistive element (hereinafter referred to as "MR element") and the like are formed on a linear surface of said ceramic rod. thing. A large number of element parts are simultaneously formed on a disc-shaped ceramic substrate, and the ceramic substrate is...
