摘要： A head stack assembly for mounting to a pivot bearing cartridge in a disk drive includes a coil having opposite electrical ends and a unitary molded plastic E-block fabricated from a first thermoplastic material containing electrically conductive filler material such that the E-block is electrically conductive. The E-block defines a generally cylindrically shaped body portion and a plurality of elongated arms, the body portion having a pivot bore for receiving the pivot bearing cartridge, a plurality of spaced-apart arm-support regions, and a surface defining a mounting site. Each arm is cantilevered from a respective one of the arm-support regions to project radially away from the pivot bore. The head stack assembly further includes an overmolded coil frame securing the coil to the body portion such that the coil is cantilevered to project radially away from the pivot bore. The overmolded coil frame is fabricated from a second thermoplastic material and is electrically non-conductive. The head stack assembly further includes a flex circuit cable having a portion secured at the mounting site, the flex circuit cable including a plurality of conductors, an electrical path from a first one of the conductors to provide ground potential to the E-block, and a pair of electrical paths from a second and a third of the conductors to the opposite electrical ends of the coil.

摘要： A novel disk drive enclosure includes a disk drive base having a bottom portion and four side walls that define a cavity therebetween. At least one disk is mounted in the cavity. The disk drive also includes a top seal that includes a peripheral portion that overlies each of the four side walls and a central portion that spans the cavity. A metal flange protrudes from all four side walls of the disk drive base, and is folded over the peripheral portion of the top seal along all four side walls. The top seal is continuously adhered to the metal flange along an entire length of all four side walls. The disk drive enclosure encloses helium gas.

摘要： A disk drive includes an opaque cover secured to a base, where the opaque cover has an opening. A see-through insert, which includes an electrically conductive material, is affixed to the opaque cover over the opening. The electrically conductive material may be a coating applied to the see-through insert which, in one embodiment is a polymer coating having a certain surface resistivity. Alternatively, the coating's ESD-dissipative properties may be due to the presence of sputtered gold, sputtered indium tin oxide or a metal film. The electrically conductive material may alternatively be embedded in the see-through insert.
