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 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： A thermally-assisted recording (TAR) disk drive uses a “wide-area” heater with “shingled” recording. In shingled recording, the write head pole tip is wider than the read head in the cross-track direction and writes magnetic transitions by making a plurality of consecutive circular paths that partially overlap. The non-overlapped portions of adjacent paths form the data tracks, which are thus narrower than the width of the write pole tip. The data tracks are grouped into annular bands and when data is to be rewritten, all of the data tracks in an annular band are also rewritten. The wide-area heater may be a waveguide with an output end that generates a heated area on the disk recording layer which is wider than the cross-track width of the write pole tip. It has been determined that the use of a wide-area heater with shingled recording does not result in any significant adjacent track erasure (ATE).

摘要翻译： 热辅助记录（TAR）磁盘驱动器使用“广域”加热器，“带状”录音。 在带状闪烁的记录中，写头磁极尖在交叉磁道方向上比读取头宽，并且通过使多个部分重叠的连续圆形路径写入磁转变。 相邻路径的非重叠部分形成数据轨道，因此比写入磁极尖端的宽度窄。 数据轨道被分组成环形带，并且当数据被重写时，环形带中的所有数据轨迹也被重写。 广域加热器可以是具有输出端的波导，该输出端在盘记录层上产生比写极尖的横越轨道宽度更宽的加热区域。 已经确定，使用具有带灰度记录的广域加热器不会导致任何显着的相邻轨道擦除（ATE）。

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： 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.
