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 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。
