Title: Thin-film magnetic head, head gimbals assembly, and hard disk drive
Inventor: YAMANAKA NOBORU
IPC: G11B5/105
Filed: 2003-02-26
Abstract: <P>PROBLEM TO BE SOLVED: To provide a thin-film magnetic head or the like capable of making very small the interval between an electromagnetic conversion element or a magnetoresistance effect element and a recording medium.  <P>SOLUTION: Since a heat generation layer 80 is energized to thermally expand a head main body, a magnetoresistance effect element or an electromagnetic conversion element is projected from the head main body toward a recording medium side (ABS surface side). By controlling the amount of electricity supplied to the heat generation layer 80, the distance between the magneto-resistance effect element or the electromagnetic conversion element and the recording medium is controlled. Further, since upper and lower parts 186 and 187 meander very close to each other in the heat generation layer 80, a magnetic field generated by the upper part 186 and a magnetic field generated by the lower part cancel each other as the Ampere's right-handed screw law teaches. Thus, the leakage of the magnetic field is reduced to make an adverse effect on a recoding head part or the magnetoresistance effect element minimal.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
