摘要： Embodiments of the present invention provide a suspension assembly having a dielectric limiter. According to one embodiment, the suspension assembly includes a load beam and a flexure assembly. The flexure assembly includes a metal layer where there are formed a fixing portion fixed to the load beam, main rings, and extending from the fixing portion, sub-rings, and a flexure tongue having moving-side limiter coupling portions defined thereon. Fixing-side limiter coupling portions are defined at the main rings. Dielectric limiters each have a gross length larger than a between-coupling-portions distance between a fixing-side limiter coupling portion and a moving-side limiter coupling portion, and couple the fixing-side limiter coupling portion to the moving-side limiter coupling portion.

摘要： A near-field transducer (NFT) has a primary tip that concentrates the oscillating charge of the NFT onto a substrate, such as magnetic recording medium, to heat regions of the medium, and a secondary tip. The secondary tip is located close to a temperature sensor, such as an electrical conductor whose resistance varies with temperature. The temperature sensor senses heat from the secondary tip and thus properties of the substrate like surface topography and the presence or absence of metallic material. The NFT can be part of a bit-patterned media (BPM) thermally-assisted recording (TAR) disk drive. The temperature sensor output is used to control the write pulses from the disk drive's write head so the magnetic write field is synchronized with the location of the magnetic data islands.

摘要： Embodiments of the present invention securely latch an actuator rotated by an external impact. In an embodiment of the present invention, a latch and an actuator have a structure in which the latch can latch the actuator at two different swing angles. The swing angle of the latch is an angle in rotation centered on a rotational shaft (rotation angle). The latch may be engaged with the actuator at a shallow angle, or the latch may be engaged with the actuator at a deeper angle. Since the latch is able to latch the actuator at different swing angles, the actuator can be securely latched.

The hard-disk drive includes a phase-detecting unit which is configured to detect a phase of the write-clock signal when the magnetic-recording head reaches an end point of a predetermined range. The hard disk drive includes a determination-processing unit which is configured to determine success of data writing based on a difference between an expected value and a detected value of the phase of the write-clock signal.

摘要： Methods of recording head fabrication are provided to fabricate a region of separation material between a write pole and a shield of a write head that forms a controlled spacing between the write pole and the shield of the write head. The method comprises forming a mask structure having an opening exposing a write pole of the write head and forming separation material above the portions of the write pole exposed by the opening. The method further comprises removing the mask structure and forming a shield of the write head above the separation material. The separation material forms a spacing between the write pole and the shield, which controls the amount of flux from the write pole absorbed by a shield (e.g., a wrap around shield) of the write head.

摘要： A hard disk drive (HDD) minimizes the effects of far track erasure (FTE) by counting the number of writes to the data tracks and incrementing counters based on the known effect of FTE on each track. The extent of the FTE effect is determined for each track within a range of tracks of the track being written, and based on the relative FTE effect for all the tracks in the range a count increment (CI) is determined for each track within the range. A counter is maintained for each track. For every writing to a track, a count for each track within a range of the track being written is increased by the CI value associated with the track number within the range. When the count value for a track reaches a predetermined threshold the data is read from that track and rewritten, preferably to the same track.
摘要翻译：硬盘驱动器（HDD）通过根据每个轨道上已知的FTE效应计数对数据磁道的写入次数和递增计数器，从而最大限度地减少了远跟踪擦除（FTE）的影响。针对正在写入的磁道的磁道的范围内的每个磁道确定FTE效应的范围，并且基于对该范围内的所有磁道的相对FTE效应，对该范围内的每个磁道确定计数增量（CI）。为每个轨道维护计数器。对于对轨道的每次写入，在被写入的轨道的范围内的每个轨道的计数增加与该范围内的轨道号相关联的CI值。当轨道的计数值达到预定阈值时，从该磁道读取数据并将其重写，优选地改写为相同的轨道。
