摘要： The head-slider is configured to receive an air-stream produced by rotation of a magnetic-recording disk and is configured to fly in proximity with a recording surface of the magnetic-recording disk. The head-slider includes a trailing edge on an outflow side of the air-stream, and a disk-facing surface that is configured to face the recording surface of the magnetic-recording disk. A low-surface-energy film is disposed on a portion of a trailing-edge side of the head-slider that is in contact with a boundary between the trailing edge and the disk-facing surface. The low-surface-energy film has a lower surface energy than other portions of the trailing-edge side where the low-surface-energy film is not disposed.

摘要： A method for measuring a change of a clearance between a head and a disk. The method includes reading a preliminarily written data string for clearance measurement on a disk to obtain a first measured value corresponding to a clearance, and writing a new data string for deterioration check onto the disk and reading the data string for deterioration check to obtain a second measured value corresponding to the clearance. The method also includes determining a deterioration of the data string for clearance measurement from a difference between the first measured value and the second measured value, measuring a clearance change using the data string for clearance measurement by a normal operation if the determination is that the data string for clearance measurement has not deteriorated, and measuring a clearance change by an operation different operation if the determination is that the data string for clearance measurement has deteriorated.

摘要： Embodiments of the present invention relate to retracting a magnetic head of a disk drive device to a retract position in accordance with a fall state, and to suppressing the performance degradation due to erroneous fall determinations as well as occurrence of damage by a head-disk crash. According to one embodiment of the present invention, in a Hard Disk Drive (HDD), a servo controller moves a head slider to a cylinder at the side of a ramp at a predetermined timing that a fall determiner determines that it is falling and an unload controller starts an unload process. This shortens the time between determination by the fall determiner that it is falling to retraction of the head slider to the retract position. Furthermore, it prevents increase of the erroneous determinations by relaxing the fall determination condition for safety. Also, it shortens the time that the head slider returns to the initial position before the seek in case that it is not determined that it is falling.
摘要翻译：本发明的实施例涉及根据跌倒状态将盘驱动装置的磁头回缩到缩回位置，并且抑制由于错误的下降判定引起的性能下降以及头盘崩溃的损坏的发生。根据本发明的一个实施例，在硬盘驱动器（HDD）中，伺服控制器在预定定时将磁头滑块移动到斜坡侧的气缸，以便下降确定器确定其正在下降并且卸载控制器启动卸载过程。这缩短了下降确定器确定其下降到头部滑块缩回到缩回位置之间的时间。此外，通过放松用于安全的跌倒判定条件，防止了错误判定的增加。而且，如果没有确定它正在下降，它会缩短磁头滑块在搜索之前返回到初始位置的时间。

摘要： A magnetic disk drive includes a magnetic disk and a femto slider. The magnetic disk has a minimum track linear velocity of 1 to 5 m/s. In one embodiment, the magnetic disk drive includes a negative pressure type femto slider and adopts a load/unload method. A gram load “GL” of a head suspension assembly HSA is set at a value exceeding about 3 mN and smaller than about 15 mN and a pitch static attitude “PSA” (deg) and pitch stiffness “Kp” (Nm/deg) satisfy the expression ((PSA×Kp)/GL)
摘要翻译：磁盘驱动器包括磁盘和毫微微滑块。磁盘具有1至5m / s的最小轨道线速度。在一个实施例中，磁盘驱动器包括负压型毫微微滑块，并采用加载/卸载方法。磁头悬挂组件HSA的克负载“GL”被设定为超过约3mN且小于约15mN的值，并且俯仰静态姿态“PSA”（deg）和俯仰刚度“Kp”（Nm / deg）满足表达式（（PSAxKp）/ GL）<0.25mm。结果，可以防止毫微微滑块假定称为双稳态高度的元稳定飞越高状态。此外，通过将俯仰静止姿态“PSA”设定为大于0度的值，可以防止滑块与称为半稳定阻力的磁盘表面发生元稳定接触的状态。
