    摘要： A thermally-assisted recording (TAR) disk drive uses “shingled” recording and a rectangular waveguide as a “wide-area” heat source. The waveguide generates a generally elliptically-shaped optical spot that heats an area of the recording layer extending across multiple data tracks. The waveguide core has an aspect ratio (cross-track width to along-the track thickness) that achieves the desired size of the heated area while locating the peak optical intensity close to the trailing edge of the write pole tip where writing occurs. The large cross-track width of the waveguide core increases the volume of recording layer heated by the optical spot, which reduces the rate of cooling. This moves the peak temperature point of the heated area closer to the write pole tip and reduces the temperature drop between the peak temperature and the temperature at the trailing edge of the write pole tip where writing occurs.

    摘要： The present invention generally relates to fabricating a bond pad for electrically connecting a laser diode to a slider and a TAR head in a HDD. The bond pad is deposited on a surface of the head that is perpendicular to the air bearing surface (ABS). The head is diced and lapped to expose the bond pad on a top surface of the head and mounted on a slider. The laser diode and a sub-mount may be coupled to the top surface of the slider—i.e., the surface opposite the ABS—by connecting to the bond pads. Specifically, both the laser diode and the sub-mount have electrodes thereon that are perpendicular to the bond pads. Conductive bonding material is used to bond the laser diode and the sub-mount to the bond pads.

    摘要： The present invention generally relates to electrically connecting a laser diode to a slider and head assembly of a TAR head in a HDD. The laser diode is coupled to a sub-mount. The laser diode and the sub-mount are coupled to the top surface of the slider and/or the head assembly. Either the slider, the head assembly or both have bond pads exposed through their respective top surfaces to provide an electrical connection to both the laser diode and the sub-mount. Both the laser diode and the sub-mount have electrodes thereon that are perpendicular to the bond pads and are in contact with the bond pads. Conductive bonding material is used to not only bond the laser diode and the sub-mount to the bond pads, but also to electrically connect the bond pads to the electrodes.

    摘要： Approaches for a hard-disk drive (HDD) baseplate comprising a recessed region that provides additional clearance for a disk. The protective enclosure of the HDD comprises a baseplate. The surface of the baseplate, which opposes a magnetic-recording disk, comprises a recessed region near the outer diameter (OD) of the magnetic-recording disk. The recessed region prevents the disk from being damaged through inadvertent physical contact with the baseplate, which may arise when the HDD receives a mechanical shock. The recessed region may be designed to minimize the damage to the disk if physical contact between the disk and the baseplate does occur. The recessed region may have a variety of shapes, such as a circular indentation or one or more non-contiguous regions in the baseplate where physical contact between the disk and the baseplate is deemed likely to occur.
