ABSTRACT:
A disk drive includes a cast base upon which is mounted the disk stack-spindle assembly and the actuator assembly and a cover that is loosely received by the cast base to form the head-disk enclosure. The cover is secured and sealed to the cast base by a malleable metal foil tape that surrounds the enclosure and continuously overlies the interface between cover and base. The tape complies with the surface irregularities and does not creep, to provide permanent shielding and sealing between base and cover. Further, cables exiting the enclosure may be sealed using a piece of double sided adhesive which is interposed between cable and casting followed by application of the malleable foil tape thereover. Thus in a compact device, no significant thickness is added to the enclosure wherein a maximum available height is used to house the stack of disks while providing noise and EMC shielding in addition to securing and sealing the cover.
