    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： A combined bulk thermal-assister and bulk eraser. The bulk thermal-assister is configured to produce a temperature in a magnetic-recording disk in a hard-disk drive when the hard-disk drive is disposed in the bulk eraser. The temperature is about equal to a second temperature greater than a first temperature of the magnetic-recording disk. The bulk eraser is configured to erase recorded information from the magnetic-recording disk at the second temperature. The second temperature lowers a coercivity of the magnetic-recording disk so that, when recorded information is erased from the magnetic-recording disk at the second temperature, recorded information on the magnetic-recording disk is erased from a second magnetic-recording track in closer proximity to an inside diameter of the magnetic-recording disk than a first magnetic-recording track from which recorded information on the magnetic-recording disk may be erased, if recorded information were erased from the magnetic-recording disk at the first temperature.

    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： 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.

    摘要： A method for neutralizing the flying height sensitivity associated with thermal pole-tip protrusion (T-PTP) of an air bearing slider comprises creating head material data and air bearing surface (ABS) compensation data, based on which a head/ABS design is created. The head material data comprises at least one material property that is dependent on the manner in which the material is fabricated, such as the coefficient of thermal expansion of a material deposited using a certain deposition process. The ABS compensation data comprises data about how respective ABS features affect air bearing pressure and, therefore, ABS compensation. A protrusion profile is determined for the head/ABS design, and whether or not this protrusion profile meets particular design criteria is then determined. The head/ABS creating and determining process can be iterated if necessary to arrive at a head/ABS design which provides neutral flying height sensitivity to a range of operational temperatures.
