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 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 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 compliant, flexible air bearing slider (ABS) reduces the contact forces between the slider and disk, thereby reducing excessive burnishing and wear and increasing the reliability of the slider. According to an embodiment, an ABS has at least one “compliance-enhancing feature” which reduces the bending mode vibration frequency of the slider. By causing the slider to flex, and bringing the bending mode vibration frequency closer to the pitch 2 eigenmode frequency, coupling of the different vibration modes can be obtained. Thus, the different vibration modes can effectively dampen each other and result in reduced contact forces between the slider and disk.
摘要翻译：兼容柔性的空气轴承滑块（ABS）可减少滑块和圆盘之间的接触力，从而减少过度抛光和磨损，并提高滑块的可靠性。根据实施例，ABS具有至少一个柔顺增强特征，其减少滑块的弯曲模式振动频率。通过使滑块弯曲，并使弯曲模式振动频率更接近于本征模式频率，可以获得不同振动模式的耦合。因此，不同的振动模式可以有效地相互阻尼并且导致滑块和盘之间的接触力减小。

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： In a method for writing data to a disk drive, a selected portion of a surface of a rotating disk of the disk drive is contacted with a designated contact region of a slider. An aspect of the contact is controlled to regulate frictional heating of the selected portion such that a magnetic field required to write data to the selected portion is reduced to a level which permits writing of data in the selected portion. Data is written on a frictionally heated track in the selected portion.

摘要： An apparatus, system, and method for measuring thermally induced electric resistance changes in thermally assisted magnetic recording are disclosed for monitoring laser light output in thermally assisted magnetic recording disk drives. An electrical lead is coupled to a read/write head element. A first electrical resistance in the read/write head element is measured. The read/write head is heated by a laser and a second electrical resistance in the read/write head element is measured. The electrical resistance may be monitored at regular intervals when the read/write head element is on the ramp or the electrical resistance measurements may be continuously monitored as the read/write head flies over the magnetic media.
