摘要： Approaches for protecting a component when a hard-disk drive (HDD) experiences a mechanical shock. An HDD includes a suspension comprising a load beam, a gimbal, and a flexure tongue. A component, such as a microactuator, is mounted on the suspension. The flexure tongue extends to at least the edge of the microactuator that is furthest from the gimbal. The flexure tongue prevents the microactuator from contacting the load beam when the HDD receives a mechanical shock. Alternately, the flexure tongue may comprise a tip portion that extends beyond the edge of the microactuator that is furthest from the gimbal, and the tip portion of the flexure tongue may deform to act as shock absorber when the HDD receives a mechanical shock. Alternately or additionally, a padding material may be used to prevent the microactuator or the flexure tongue from contacting the load beam when the HDD receives a mechanical shock.

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： Embodiments in accordance with the present invention provide a magnetic head slider to be easily mounted on or dismounted from a suspension and can hold a magnetic head slider so as not to be removed due to a shock resultant from handling during a characteristic test and a manufacturing process. A load beam is formed with protruding portions on both sides. A flexure includes a frame portion, a plate portion, a spring portion, an E-shaped pressing portion, and a probe portion. The plate portion extends from a guide portion of the frame portion. The probe portion may be formed by partially cutting out the frame portion. A limiter is formed on both sides of the plate portion. The limiter protrudes from the rear of the load beam and has a hook-shaped tip. The hook-shaped portion of the limiter engages with the protruding portion 6 of the load beam to limit excess vertical movement of the flexure. A gap may be formed between the limiter and the protruding portion.

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.
