摘要:
A disk drive including a disk drive base and a cover attached to the disk drive base. The disk drive further includes a rotatable disk including a disk surface extending to an outer periphery. The disk drive further includes a spindle motor including an axis of rotation. The spindle motor is rotatably coupled to the disk drive base for rotating the disk about the axis of rotation. The disk drive further includes a shroud surface concentrically formed about and adjacent the outer periphery. The disk drive further includes a cavity formed in the shroud surface. The cavity extends to a cavity opening adjacent the outer periphery. The disk drive further includes an airflow diverter element extending from the cover towards the disk surface radially between the cavity opening and the axis of rotation for diverting disk rotation induced airflow adjacent the disk surface.

A disk drive includes a printed circuit board, an integrated circuit coupled to the printed circuit board, and a disk drive base coupled to the printed circuit board. The disk drive base includes a platform, the platform having a first surface elevated towards the printed circuit board and a second surface further elevated towards the printed circuit board relative to the first surface, the platform being generally aligned with the integrated circuit along an axis normal to the first surface.

A disk drive includes a disk drive base and an actuator that is rotatably coupled to the disk drive base. The actuator has an axis of rotation. The disk drive further includes a latch. The latch includes a fixed portion that is firmly coupled to the disk drive base, and a latching portion. The latch further includes a latch arm portion connecting the latching portion to the fixed portion. The latch arm portion includes a hinge region. The latch arm portion is thinner in a direction normal to the axis of rotation in the hinge region than the latch arm portion is outside of the hinge region. The latch arm portion, the latching portion, and the fixed portion are a single component having material continuity rather than an assembly of sub-components.

A disk drive includes a disk drive base. The disk drive further includes a cover. The disk drive further includes a rotary actuator rotably coupled to the disk drive base and the cover. The rotary actuator is disposed between the disk drive base and the cover. The disk drive further includes a post attached to the disk drive base. The post is positioned to limit a pivot arc of the rotary actuator in at least one direction of rotation. The post includes a post distal end extending away from the disk drive base and attached to the cover.

A disk drive includes a disk drive base including a pair of tab engagement slots. The disk drive further includes a printed circuit board assembly and a PCBA shield including a shield body having opposing first and second ends. The shield body is disposed against the printed circuit board assembly with the printed circuit board assembly between the PCBA shield and the disk drive base. The PCBA shield includes a pair of tabs extending from and integrally formed with the shield body at the first end. The tabs each are respectively disposed in the tab engagement slots for attaching the PCBA shield to the disk drive base. The tabs each are cooperatively sized and configured with the respective tab engagement slots to apply a force between the first end of the shield body and the printed circuit board assembly. The second end is attached to the disk drive base.

Disclosed is a continuous separator plate for use with a disk drive. The continuous separator plate includes a substantially circular continuous outer circumference and a substantially circular continuous inner circumference. A continuous radial portion may be defined between the substantially circular continuous outer and inner circumferences. The continuous radial portion is to be disposed between at least one disk of the disk drive and either the cover or the base of the disk drive, respectively. Further, the continuous radial portion includes a disk side that faces the at least one disk and an opposite side that faces either the cover or the base, respectively. The continuous separator plate further includes a head stack assembly (HSA) accommodation section to accommodate an HSA.

A novel disk drive includes a flex cable having a first end portion fixed to an actuator assembly, a second end portion fixed to a flex cable bracket, and a free portion between the first and second end portions. The free portion joins the second end portion at a flex exit location. The flex cable bracket includes a flex alignment post that protrudes into a corresponding hole in a disk drive base. A distance between the flex exit location and the actuator pivot axis is at least 4 times greater than a distance between the flex exit location and the flex alignment post.

A disk drive includes a cast baseplate, and a disk having a major surface and an outer circumference. The cast baseplate includes a casting inlet gate region, a planar area underlying the disk, an arcuate shroud wall that is substantially orthogonal to the planar area, and an arcuate groove immediately adjacent the planar area. The planar area is separated from the disk major surface by less than 0.8 mm. The arcuate shroud wall is disposed less than 0.8 mm from the disk outer circumference, and includes a first shroud wall portion and a second shroud wall portion. The first shroud wall portion is more proximate to the casting inlet gate region than is the second shroud wall portion. The arcuate groove is immediately adjacent the first shroud wall portion, and defines a groove depth in the range 0.2 mm to 2 mm relative to the planar area.

A hard disk drive recirculation filter is disposed on a housing surface of a disk drive assembly oriented adjacent to one or more disk surfaces. In one embodiment, the recirculation filter is a pocket filter having a filter support component and a filter element. The filter support includes an inlet, a top surface and a bottom surface, where the bottom surface is used to adhere the pocket filter to the housing surface. The top surface is adapted to adhere the filter element thereto, thereby forming a pocket into which rotationally-induced airflow may enter.

A radial top cover gasket is used for sealing a disk drive assembly. In one embodiment, a disk drive assembly includes a baseplate having a sidewall disposed about a periphery of the baseplate. The disk drive further includes a top cover that is disposed within the sidewall of the baseplate. A gasket is then radially compressed between the top cover and an inner face of the baseplate sidewall.
