Abstract:
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.
