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.

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 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.
摘要翻译： 用于安装到盘驱动器中的枢转轴承筒的头部堆叠组件包括具有相对电端的线圈和由包含导电填充材料的第一热塑性材料制成的整体模制塑料E形块，使得E形块是导电的 。 E形块限定了大致圆柱形的本体部分和多个细长臂，主体部分具有用于接收枢转轴承筒的枢轴孔，多个间隔开的臂支撑区域，以及限定安装位置的表面 。 每个臂从相应的一个臂支撑区域悬臂以径向远离枢轴孔径突出。 头部堆叠组件还包括将线圈固定到主体部分的包覆成型的线圈框架，使得线圈被悬臂以径向远离枢转孔径突出。 包覆成型的线圈框架由第二热塑性材料制成并且是非导电的。 头部堆叠组件还包括柔性电路电缆，其具有固定在安装位置处的部分，柔性电路电缆包括多个导体，来自第一导体的电路以向E块提供接地电位，以及 从导体的第二和第三导体到线圈的相对电端的一对电路径。
