摘要： Embodiments of the present invention provide a rotating disk storage device adopting a thin yoke structure. In one embodiment, the yoke structure of a voice coil motor includes a base of a casing formed from a ferromagnetic material; an auxiliary yoke disposed so as to be magnetically coupled to the base; a magnet disposed so as to be magnetically coupled to a front surface of the auxiliary yoke; and a main yoke provided with yoke legs magnetically coupled to the auxiliary yoke and an opposing surface that confronts a front surface of the magnet. In addition, a yoke gap is defined between the opposing surface and the front surface of the magnet. The base and the auxiliary yoke form a magnetic path, which allows a dedicated yoke on a lower portion to be eliminated.

摘要： Embodiments of the invention provide a retaining ring attaching device capable of improving assembling efficiency and a data storage device fabricating method. In one embodiment, a C ring attaching device included in a hard disk drive assembling apparatus expands a C ring, puts the expanded C ring on a pivot, and contracts the C ring on the pivot. The C ring attaching device moves chuck arms holding the C ring such that the C ring is moved so that a gap in the C ring moves away from the pivot while the C ring is being contracted.

摘要： Embodiments of the invention prevent the magnetic head from dropping to the magnetic disk when it is retracted. If the power supply Vcc to the drive is interrupted, a power supply voltage detecting section detects that the power supply to the drive is interrupted. A control section sets switches to the ON state in order to discharge the charged retract capacitor and supply the discharge current to a voice coil. The control section retains the switches in the ON state for a period which is determined based on the discharge period specifying control data stored in a register and the count signal from a counter. A voice coil motor, to which the current is supplied, turns the actuator in the unloading direction to retract the actuator to the ramp.
