Patent ID: 7538978

Claim:
A heat assisted magnetic recording head comprising: a magnetic recording element including a recording magnetic pole and a magnetic read element that are mounted on a floating slider; a laser diode serving as a light source of a heating laser beam; and an irradiating optical waveguide, arranged close to the magnetic recording element, for directing the heating laser beam to a minute magnetizing region of a magnetic recording medium in which recording is performed by the recording magnetic pole, wherein an optical waveguide for directing the heating laser beam to the irradiating optical waveguide is provided on a rear side of the irradiating optical waveguide; the floating slider is supported by a surface of a suspension; a heat sink is supported by another surface of the suspension; the laser diode is supported by a side surface of the heat sink; and the heating laser beam emitted from the laser diode is incident on an incident surface being located on an opposite side of the irradiating optical waveguide through a through hole formed in the suspension.
