    摘要： A process for fabricating a mold for an aspherical microlens having a desired aspherical and smooth surface, the lens having an effective diameter of 1 mm or smaller and a thickness of 0.5 mm or greater. A double-layer mask layer is formed on a single crystal silicon substrate, and anisotropic etching and isotropic etching are carried out using a first mask layer so as to form a concave portion that is a little smaller than the size of a desired microlens mold. Isotropic etching is then carried out using a second mask layer so as to enlarge the concave portion, thereby obtaining a microlens mold having desired dimensions.

    摘要： There is provided a compact optical disc apparatus having a small footprint actuator. A tracking coil of a swing arm-type actuator is disposed substantially perpendicular to an arm and on the opposite side to an optical disc loading slot with respect to the line connecting the center of rotation of the optical disc to the center of swing movement of the actuator. A pair of permanent magnets are disposed such that they face the tracking coil and they are opposite in polarity. The tracking coil is disposed on both the permanent magnets such that the tracking coil straddles the boundary of the pair of permanent magnets.

    摘要： In a magnetic head supporting apparatus having a second actuator for fine movement in addition to a first actuator having a voice coil motor for coarse movement, the second actuator is fixed so as to bridge the upper surface of a suspension and the upper surface of a suspension supporting member to support the suspension, and the second actuator is a plate-shaped structure which has two polarization regions separated by a non-polarized region and is formed by laminating piezoelectric flat plates in which the polarizing directions and the directions of electric fields to be applied are thickness directions. Thus, a magnetic disk apparatus which can be driven by a low voltage, a displacement in the vertical direction of the suspension is small, a productivity is high, and a recording density is high can be realized.

    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： A head assembly for a data storage device. The head assembly has a suspension. The head assembly also includes a contact pad coupled to the suspension. The head assembly also includes a slider. The slider is coupled to the suspension at the slider mounting point. The slider mounting point is at least partially bounded by polyimide standoffs. The polyimide standoff closest to the contact pad is positioned to reduce the effect of the solder shrinkage moment.
