    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： Due to the raised operating rotation speed, it has become an important technical theme to reduce fluid vibrations caused by high speed air flows passing the wiring extension in a head gimbal assembly in order to raise the positioning accuracy for higher density recording. Embodiments of the present invention provide a spring structure to the wiring extension. In a wiring extension holding section formed on the carriage side, the wiring extension is retained at the center of the groove of the holding section by the repulsive force of spring members. By preventing the wiring extension from being directly subject to high speed air flows generated by a high-speed rotating disk, this structure is intended to suppress vibrations of the wiring extension caused by high-speed air flows passing the wiring extension.

    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.

    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： A magnetic disk apparatus of the present invention is equipped with a microactuator for micro motion using piezoelectric elements in addition to a coarse adjustment actuator such as a voice coil motor or the like, eliminates parts that slide between the microactuator and surrounding members, and alleviates stress on the piezoelectric elements even if an impact is given to the magnetic disk apparatus. Thus, a first actuator fixing portion on a carriage side and a second actuator fixing portion on a magnetic head side of a microactuator mounting portion are coupled with a plurality of flexible coupling portions and coupling portions are placed outside the microactuator in substantially symmetric with respect to a centerline in a longitudinal direction of a suspension.
