    摘要: A portable, small magnetic disk drive to be mounted on a portable device operates silently at low power consumption. In one embodiment, a spindle motor is fixed to the bottom wall of a metal base plate formed in the shape of a box by press working. The spindle motor is provided with a fluid dynamic bearing (FDB). A spindle hub is supported on the FDB, and a small magnetic disk having a diameter of about 1.8 in. (45.7 mm) or below is mounted on the spindle hub and is fastened to the spindle hub with a top clamp. The rotating speed of the spindle motor is about 4200 rpm or below. Gram load for pressing a magnetic head toward the magnetic disk is about 0.5 gf or above and less than about 1.0 gf.

    摘要: Embodiments of the present invention help to effectively remove adhesion on a head slider. In an embodiment of the present invention, a hard disk controller/multiprocessing unit (HDC/MPU) raises the temperature on the surface of a head slider with a heating element on the head slider to remove adhesion on the head slider while an actuator stays on a ramp. The HDC/MPU varies the amount of heat in accordance with the temperature sensed by a temperature sensor. This achieves removal of the adhesion on the head slider, maintaining reliability.

    摘要: In the present invention four thrusters are provided as a group of thrusters for collision avoidance. These thrusters contain a component of translational thrust for collision avoidance injection in their respective outputs, and are capable of simultaneously generating posture control torque around two coordinate axes, which are orthogonal to a thrust axis, in order to maintain the directional stability of the thrust axis during the injection. When abnormality arises in a group of thrusters for ordinary use, collision avoidance is executed by replacing all the thrusters for ordinary use by these thrusters for collision avoidance.
