摘要： Embodiments of the present invention help to prevent dropout of a head slider from an micro electrical mechanical system (MEMS) and damage of the MEMS. In an embodiment of the present invention, a suspension for a slider dynamic electric test (DET) comprises an MEMS for supporting a head slider. The MEMS has a clamper for holding a head slider and the clamper moved by an external force can attach or detach a head slider. The suspension comprises limiters for limiting the clamper's lateral movement. The limiters limit the clamper's undesirable movement, which prevents the clamper's lateral movement in attaching a head slider, a head slider's dropout and the MEMS's damage caused by a contact with a magnetic disk, or a head slider's dropout and the MEMS's damage in handling.

摘要： Embodiments of the present invention relate to approaches to effectively let noise on a head slider bonded to a silicon substrate of a microactuator, escape to the ground. A head gimbal assembly (HGA) according to an embodiment of the present invention comprises a microactuator bonded to a gimbal tongue. The microactuator comprises a piezoelectric element and a movable part for moving in response to expansion or contraction of the piezoelectric element. The motion of the movable part causes a head slider to slightly move. The microactuator further comprises a conductive path including an impurity-containing silicon layer formed on the silicon substrate. The conductive path transmits electric charge of the head slider to a suspension. The conductivity of the impurity-containing silicon layer is lower than the one of the silicon substrate so that the noise charge of the head slider may escape to the suspension.

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： 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 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.
