摘要:
The present invention provides a depopulation version hard disk drive apparatus that has a reduced number of magnetic heads and suspension arms from a standard hard disk drive apparatus, wherein the magnetic head can still be properly controlled during a loading state. The hard disk drive apparatus includes a ramp which interfaces with the suspension arm when loading and unloading the arm. An angle of a second slope surface 61c of the ramp in the depopulation version hard disk drive is set larger than that of the corresponding slope surface of the ramp 6 the a standard version hard disk drive.

A magnetic circuit is provided in an enclosure that can efficiently generate magnetic flux from the enclosure, configuring a magnetic disk, to a magnetic disk. Thus, by providing such a magnetic circuit, a magnetic field different from that in other enclosure parts, that is, a local magnetic field, is generated from the magnetic circuit in case the disk device is set in an external magnetic field. Hence, this local magnetic field can effectively erase data in the magnetic disk. In particular, since the local magnetic field is generated even if the external magnetic field is weak, it is possible to not only suppress the demagnetization of permanent magnets used in the spindle motor at minimum, but also effectively erase data in the magnetic disk.

A disk drive head assembly enables adjustment of a center of gravity of the head assembly of a depopulation version, while suppressing an occurrence of a resonance frequency affecting the performance of the disk drive apparatus. The head assembly for the data storage media includes: magnetic heads for reading/writing data from/to the data storage media, arms to which the magnetic heads are attached, a pivot shaft holder for supporting the arms, a coil for a voice coil motor extended from the pivot shaft holder, and a counter weight provided at a predetermined position opposite to a coil for the voice coil motor with respect to the pivot shaft holder.

An apparatus to guide and lock a rotary actuator at a limiting rotational angle in a disk storage. A rotary actuator is attached within a housing so that it is rotatable on a pivot shaft. An iron piece is rotated integrally with the rotary actuator and is attracted in magnetic cooperation with a lock magnet. A retract magnet is attached to housing and assists in rotation of the actuator during an unload operation in which the rotary actuator is removed to a load/unload ramp.

Embodiments in accordance with the present invention reduce the height of a head gimbal assembly (HGA) while maintaining the rigidity of a load beam. According to one embodiment of the present invention, an HGA includes a slider, a flexure, and a load beam. The load beam includes a flange formed to protrude to the opposite side to a magnetic disk at the edge of the load beam extending in the length-wise direction. The load beam has a recessed portion opened to the side opposing the magnetic disk and having an opening area larger than the area of the back surface of the slider opposing the flexure. The slider is provided in the recessed portion so that the position of the surface of the load beam is between a virtual surface including the surface of the slider opposing the magnetic disk and a virtual surface including the slider back surface.

Embodiments of the invention reduce the height of a ramp to provide a thin data storage device that is capable of inhibiting the deterioration of the dynamic characteristics at the time of loading/unloading. In one embodiment, a data storage device includes a head that accesses a recording region of a recording disk; a ramp that is positioned circumferentially apart from an outermost end of the recording disk to unload the head from a surface of the recording disk; and an actuator that includes a load beam for supporting the head and moves the head. The load beam includes a tab that is extended from a leading end section of the load beam, beyond the head support section of the load beam, and toward the recording disk, and slides over a ramp surface.

Embodiments in accordance with the present invention provide achieve an increase of storage capacity and thinning down of a disk drive by reducing effects from an error in an assembly position of a ramp. A data storage device according to an embodiment of the present invention includes a head, a ramp, a load beam, and an actuator. The ramp includes a portion onto which the head is retracted from a surface of a medium. The load beam includes a head support portion that supports the head and a tab disposed more on the side of a leading end than the head support portion. The tab has a leading end that slides over, while being in contact with, a sliding surface of the ramp. The actuator includes the load beam and loads and unloads the head.
