摘要： A head support mechanism includes a slider equipped with a magnetic head to read/write information from/to a magnetic disk, a load beam to provide the slider with an appropriate load, the load beam being flexible in a direction substantially perpendicular to the disk, and a microactuator mounting portion equipped with a microactuator. A first actuator fixing portion, which connects the microactuator mounting portion to a carriage, and a second actuator fixing portion on the magnetic head side of the microactuator mounting portion, which connects the microactuator mounting portion to the load beam, are coupled by two arm portions of the microactuator mounting portion. The microactuator is mounted on the microactuator mounting portion so that the microactuator does not come into contact with the microactuator mounting portion between the first actuator fixing portion and the second actuator fixing portion.

摘要： Embodiments of the invention suppress head jump at the time of application of an impact to provide for an excellent impact resistance performance in a magnetic disk device. In one embodiment, an actuator of a magnetic disk device comprises a suspension mounting the slider on a tip end side thereof to give a predetermined load to the slider, and an arm that holds the suspension, the arm being supported to be able to turn. The arm comprises two arm portions juxtaposed in a direction perpendicular to a surface of the disk, and a spacing between the two arm portions on a side of supported portions thereof in the direction perpendicular to the surface of the disk is larger than that on a side of the slider in the direction perpendicular to the surface of the disk.

摘要： Embodiments of the invention limit a pitch attitude angle of a magnetic head slider during loading without allowing gimbal stiffness of a flexure in an ordinary flying state to be increased. In one embodiment, a limiter formed by part of a flexure is disposed so as to provide a clearance from a lift tab formed by part of a load beam. A limiter clearance, if the clearance between the limiter and the lift tab is so called for convenience sake, must be maintained as a physical clearance when a magnetic head slider is in an ordinary flying state. The lift tab and the limiter are disposed on a side of an air inflow end of the magnetic head slider. The limiter clearance during unloading is thereby made small so as to allow proper and positive unloading operation. In addition, the limiter clearance made small during loading allows the absolute value of a pitch attitude angle of the magnetic head slider to be limited to a small one if the pitch attitude angle tends to become negative due to disturbances or vibration from the loading operation itself.
摘要翻译：本发明的实施例在加载期间限制磁头滑块的俯仰姿态角度，而不增加普通飞行状态下的挠曲件的万向节刚度。在一个实施例中，通过弯曲部分形成的限制器被设置成提供与由负载梁的一部分形成的升降接头的间隙。如果磁头滑块处于普通飞行状态时，如果为了方便起见，如果限位器和升降片之间的间隙被称为限位器间隙，则必须保持作为物理间隙。提升片和限制器设置在磁头滑块的空气流入端的一侧。因此，在卸载期间的限制器间隙变小，从而允许正确的和正的卸载操作。此外，限制器间隙在加载期间变小时，如果由于装载操作本身的干扰或振动而导致俯仰姿态角倾向于变为负，则磁头滑块的俯仰姿态角的绝对值将被限制为较小的。

摘要： There is provided a magnetic disk drive in which a flying-height fluctuation produced by the operation of a fine actuator is decreased, the reliability is high, and recording density is high. For this purpose, the magnetic disk drive is configured as described below. The magnetic disk drive has a suspension including a base plate connected to a carriage, a load beam fitted with a slider, and a fine actuator which is provided on the base plate and finely moves the load beam. The configuration is such that the shortest track travel time using the fine actuator is larger than the inverse number of the local maximum of a flying-height fluctuation frequency of the suspension by the fine actuator. Also, the configuration is such that the shortest track travel time using the fine actuator is larger than the inverse number of the natural frequency of first torsion mode of the suspension by the fine actuator.
