Problems solved by technology

[0012] When arbitrarily different radial direction positions of the recording medium 12, when disposing a plurality of magnetic head devices, each magnetic head device changes for conditions such as the deflection angle of the recording medium 12 and the relative walking speed, therefore, it is impossible to Under the condition of each magnetic head device is checked
[0013] In addition, it has been considered to make the recording functional part of each magnetic head and the search area of ​​the reproducing functional part be located on the circumference of the recording medium 12 with a radius of r, so that a plurality of magnetic head devices are arranged; but, because of the following reasons, this cannot be adopted. method

Embodiment Construction

[0054] figure 1 It is a plan view showing an embodiment of the inspection method of the present invention. At the front end of the supporting member 21a of the magnetic head device H1 to be inspected, a magnetic head 22a having a recording function part and a reproducing function part is supported. The support member 21a of the magnetic head device H1 is mounted on a holder 23a as a holding device, and faces the disc-shaped recording medium 24.

[0055] In addition, the magnetic head device H2 inspected at the same time as the magnetic head device H1 is supported by the holder 23b in the vicinity of the side opposite to the center O of the recording medium 24 of the magnetic head device H1. A magnetic head 22b having a recording function part and a reproducing function part is supported at the front end of the supporting member 21b of the magnetic head device H2. The recording function part and the reproduction function part of the magnetic heads 22a and 22b are, for example, an...

Abstract

A plurality of magnetic head devices H1, H2 are arranged, while their scanning regions of recording function parts and reproducing function parts of respective magnetic heads 22a, 22b installed at the magnetic head devices H1, H2 are deviated slightly from the center of a recording medium in the radial direction, in such a way that the scanning regions do not overlap.

Description

Technical field [0001] The present invention relates to, for example, an inspection method and an inspection apparatus in the manufacturing process of a magnetic head device having a recording and reproducing magnetic head used on a hard disk or the like. More specifically, it relates to an inspection method and an inspection apparatus of a magnetic head device that can improve inspection efficiency by simultaneously inspecting a plurality of magnetic head devices. Background technique [0002] Picture 9 Shows a perspective view of the magnetic head device. A flexure 2 is provided at the front end of the load beam (support member) 1 of the magnetic head device H, and the magnetic head 3 is supported by the flexure 2. The load beam 1 and the flexure 2 are elastic support members made of flat springs or the like. The mounting plate 4 is engaged with the base end of the load beam 1. [0003] On the driven end T of the magnetic head 3, a recording function part and a reproduction f...
