Patent ID: 8270262

Claim:
A thermally assisted magnetic recording head comprising: a light emitting element in which an output end for emitting light in a direction bisecting a resonator direction is formed; a sub-mount on which the light emitting element is mounted and which is mounted on a head supporting member; and a head slider which includes at least a magnetic recording element and is mounted on the sub-mount, and which receives light emitted by the light emitting element and includes a photoelectric converter emitting near-field light from a recording medium-facing surface facing a recording medium, wherein the sub-mount has a wiring line which electrically connects a terminal arranged on the head slider and a terminal arranged on the head supporting member; wherein the sub-mount has a wiring line which electrically connects a terminal arranged on the light emitting element and a terminal arranged on the head supporting member; and wherein a concave portion which opens to the head supporting member side and in which the light emitting element is stored and a through-hole which penetrates from a bottom part of the concave portion up to the head slider side are formed in the sub-mount.
