MANUFACTURING METHOD OF MAGNETIC DISK DEVICE, TEST EQUIPMENT FOR MAGNETIC DISK DEVICE, AND TEST METHOD FOR THE TEST EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of a magnetic disk device, permitting reduction in wasteful costs, when manufacturing the magnetic disk device in which a magnetic disk and an access control part therefor are included, and the control part writes servo signals on the magnetic disk after assembled, to provide test equipment of the magnetic disk device, and to provide a test method for the test equipment.;SOLUTION: Before assembling a HDA 10 in the magnetic disk device 1, a magnetic conversion characteristics of the magnetic disk 12 are tested, and on condition that the magnetic conversion characteristics of the magnetic disk 12 are reasonable as a result of the test; the HDA 10 and a processing part 30 are built in the magnetic disk device 1; and the built-in processing part 30 controls a driving part such as a VMC 16 for driving the magnetic disk 12, a processing circuit 18, a head 17, and a spindle motor 14, to write the servo signals on the magnetic disk 12.;COPYRIGHT: (C)2006,JPO&NCIPI
