Patent ID: 7894160

Claim:
A thin-film magnetic head, comprising: a reproduction element; a recording element stacked on the reproduction element, including a pair of magnetic core layers and a coil layer configured to apply a recording magnetic field to the magnetic core layers; and a heat-emitting member emitting heat by electrification configured to cause the reproduction element to project toward a recording medium by thermal expansion, wherein the heat-emitting member is disposed below the coil layer and formed of a heat-emitting member pattern of an inverse Ω shape as seen from the stacking direction, the heat-emitting member surrounding the reproduction element from both sides of a track width direction toward the rear side of a height direction; wherein the coil layer has a coil pattern formed at predetermined pitches, the heat-emitting member has an edge portion of a medium-opposed surface side that is parallel with the coil pattern, and the edge portion of the medium-opposed surface side is disposed between the pitches of the coil layer; and wherein the edge portion of the medium-opposed surface side is disposed closer to the recording medium than a contact portion connecting the pair of magnetic core layers.
