摘要： The present invention provides a crash stop which is capable of adjusting shock absorptivity by employing the same elastic material and where the mounting and demounting operations are easy. A metal pin has a recess in its intermediate portion. An elastic body has three blade portions. In a crash stop, the metal pin is press fitted into the pin inserting hole of the elastic body, and the portion between the support portion and the knob portion of the metal pin is covered with the elastic body. In the boundary between the intermediate portion of the metal pin and the elastic body, a cavity is formed. The support portion is fitted into the crash stop support hole of the base so that it can be freely pulled out and inserted. At this time, the upper end of the blade portion contacts the inner side surface of the crash stop inserting hole of the upper yoke and is contracted, and by the frictional force generated between the crash stop inserting hole and the upper end of the blade portion, the crash stop is locked. The abutting shock of the stopper arm of an actuator is absorbed with cooperation of the elastic body and the cavity.

摘要： Embodiments in accordance with the present invention provide a magnetic disk drive with sufficiently low noise. A digital/analog converter supplies to a voice coil motor (VCM) driver a control voltage comprising a first preset voltage value, a second preset voltage value, and a transition voltage value of a substantially cosine wave that interconnects the first preset voltage value and the second preset voltage value. A driving current is supplied from the VCM driver to a voice coil of an actuator assembly. Since a current not containing higher-harmonic components in a transition period flows as a VCM current that flows into the voice coil, vibromotive force can be easily suppressed by shifting a structural resonance point of the entire disk drive including the actuator assembly. In addition, since the back electromotive force occurring in an inductance element is cleared to zero during a half wavelength of period of the cosine wave, speed electromotive force can be measured by immediate shifting from a setting period to a measuring period.

摘要： Embodiments of the invention suppress the occurrence of turbulence in a disk drive. In one embodiment, an HDD includes a spindle motor for rotating a magnetic disk, and a base for housing the spindle motor therein. The base includes a first bottom surface opposed to the magnetic disk, and a second bottom surface that is opposed to the magnetic disk and that is larger in distance to the magnetic disk than the first surface. A step is formed between the first bottom surface and the second bottom surface, where rotation of the magnetic disk produces an airflow running from the first surface toward the second surface. The step is provided with upright fins extending from the first surface toward the second surface which are stood upright.

摘要： Embodiments of the present invention restrain the head position accuracy from degrading due to torsional vibration of a head supporting unit. According to an embodiment of the invention, an actuator has a twisted carriage arm. A suspension is tilted in accordance with the twist of the carriage arm. When the carriage arm and the suspension torsionally vibrate, the vibration direction tilts against the normal direction of a recording surface in accordance with the twist. This technique decreases a peak value of off-track displacement that is caused by a head slider and is dependent on relationship between a skew angle and a torsional vibration direction.
