摘要： Embodiment of the invention provides a magnetic disk drive that may suppress the decrease of a recording region by preventing a magnetic head slider from abutting a magnetic disk at the time of loading, and suppress the degradation of the flying characteristics. In one embodiment a magnetic disk drive of the present invention is provided with a magnetic head slider including a magnetic transducer, a ramp that unloads the magnetic head slider, and an actuator that moves the magnetic head slider. The magnetic head slider includes a rail surface that generates a positive pressure on an air-bearing surface, a step bearing surface, and a taper section that is formed to a slider corner section that is brought closest to the surface of a recording disk at the time of loading with a space from the rail surface and the step bearing surface.

摘要： A compact hard disk drive that operates silently at a low power consumption needs a suspension assembly that places a low load on the magnetic head. In one embodiment, a suspension assembly comprises a head arm mounted on a carriage shaft, a load beam capable of placing load on a magnetic head and serving as a beam, and a flexure assembly. The flexure assembly includes a flexure formed by processing a thin metal sheet, an insulating layer laminated to the flexure, a wiring pattern formed on the insulating layer, and a protective layer coating the wiring pattern. The flexure has a flexible part for placing load on the magnetic head, a gimbals to which the magnetic head is attached, and a base part attached to the head arm. The elastic part of the flexure generates a very load in the range of about 0.5 to about 1 g.

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。

摘要： Embodiments of the present invention help to effectively remove adhesion on a head slider. In an embodiment of the present invention, a hard disk controller/multiprocessing unit (HDC/MPU) raises the temperature on the surface of a head slider with a heating element on the head slider to remove adhesion on the head slider while an actuator stays on a ramp. The HDC/MPU varies the amount of heat in accordance with the temperature sensed by a temperature sensor. This achieves removal of the adhesion on the head slider, maintaining reliability.

摘要： Embodiments of the invention provide a rotary disk storage device in which dust particles are less likely to deposit on the air bearing surface of each head/slider. The actuator head suspension assembly is configured so as to make the skew angle of the head/slider positive at about 80% or more of all the tracks. Specifically, the actuator head suspension assembly is configured in such a manner that the distance L2 between the center of the pivot shaft and the intersection point P of the trailing edge of the head/slider is made longer than a given length or there is an angle β between the reference line Y and the pivot line Z.
