摘要： Components for, and assembly of, a thermally assisted recording device involve a laser mounted to a recording head slider. The output from the laser is directed into an optical waveguide, which delivers the laser light to the media to be written. Several challenges with thermally assisted recording are enabled by the use of a laser carrier, which holds and protects the small, relatively fragile laser and serves as a partial heat sink for the power generated by the laser. The laser, carrier and slider are bonded and can be interconnected as a unit to a suspension constituent to a hard disk drive (HDD) device.

摘要： A magnetic media for heat assisted magnetic data recording. The magnetic media includes a thermal insulation layer structure formed near the substrate of the media provide more efficient heating of the write layer by allowing less heat dissipation to the substrate. The thermal insulation layer structure can be one or more layers of an oxide such as SiO2 and one or more layers of a material such as NiTa. Increasing the number of oxide layers and NiTa layers increases the thermal insulation of the thermal insulation layer structure thereby further increasing the efficiency of the heat assisted writing.

摘要： Embodiments of the present invention help to suppress reduction of the operation quantity of a microactuator. According to one embodiment, a microactuator comprises a silicon substrate and a piezoelectric element. The silicon substrate has some rigidity and provides elastic counter force to the piezoelectric element. In the piezoelectric element, a secondary piezoelectric layer is laminated on a primary piezoelectric layer opposite from the silicon substrate. The contraction force of the secondary piezoelectric layer acts on the primary piezoelectric layer so that it bends toward the secondary piezoelectric layer opposite from the silicon substrate. When the primary piezoelectric layer expands, the contraction force of the secondary piezoelectric layer acts on the primary piezoelectric layer so that it warps against the primary piezoelectric layer.

摘要： Embodiments of the present invention relate to approaches to effectively let noise on a head slider bonded to a silicon substrate of a microactuator, escape to the ground. A head gimbal assembly (HGA) according to an embodiment of the present invention comprises a microactuator bonded to a gimbal tongue. The microactuator comprises a piezoelectric element and a movable part for moving in response to expansion or contraction of the piezoelectric element. The motion of the movable part causes a head slider to slightly move. The microactuator further comprises a conductive path including an impurity-containing silicon layer formed on the silicon substrate. The conductive path transmits electric charge of the head slider to a suspension. The conductivity of the impurity-containing silicon layer is lower than the one of the silicon substrate so that the noise charge of the head slider may escape to the suspension.
