Abstract
A DC current is supplied to the write coil of a GMR headequipped with a completed HGA (Head Gimbal Assembly). The element part of the GMR headis thereby thermally deformed. Thus deformed, the element part protrudes, abutting on a rotating laser-bump disk, above which the HGA is floating. When the element part abuts on the disk, a magnetic field (2470 gauss) that extends in a direction opposite to the magnetization direction of the fixed layer of the GMR headis applied to the top of a core slider
