Abstract

Abstract A disk drive in which the base and the cover are interconnected in spaced positions to provide a marginal, peripheral gap between confronting or adjacent faces or edges thereof. The gap is bridged, closed and sealed by means of a pressure sensitive adhesive tape, a viscoelastic tape, which is energy adsorbing to damp disk drive vibrations.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 89 words
A disk drive enclosure in which stresses are minimized, comprising: a base having a peripheral portion; a cover having a peripheral portion; means connecting said cover to said base and supporting said cover spaced from said base in a position defining a gap between said peripheral portion of said base and said peripheral portion of said cover, and a viscoelastic material having a pressure sensitive adhesive coating adhesively attached to said base and said cover at each said peripheral portion in a position bridging, closing and sealing said gap.
Claim 2
Dependent Claim 89 words
A disk drive enclosure in which stresses are minimized, comprising: a base having a peripheral portion; a cover having a peripheral portion; means connecting said cover to said base and supporting said cover spaced from said base in a position defining a gap between said peripheral portion of said base and said peripheral portion of said cover, and a viscoelastic material having a pressure sensitive adhesive coating adhesively attached to said base and said cover at each said peripheral portion in a position bridging, closing and sealing said gap.
Claim 3
Dependent Claim 42 words
The disk enclosure according to claim 1, in which: said means connecting said cover to said base comprises a plurality of flexible structures, each structure being connected at one end to said base and at the other receiving and supporting said cover.
Claim 4
Dependent Claim 16 words
The disk drive enclosure according to claim 2, in which: each flexible structure comprises a post.
Claim 5
Dependent Claim 34 words
The disk drive enclosure according to claim 2, in which: said viscoelastic material having a pressure sensitive adhesive coating is a pressure sensitive adhesive tape which comprises and energy absorbing material for vibration damping.
Claim 6
Dependent Claim 23 words
The disk drive enclosure according to claim 4, in which: said energy absorbing material comprises a soft, deformable thin film on said tape.
Claim 7
Dependent Claim 16 words
The disk drive enclosure according to claim 5, in which: said deformable thin film is aluminum.
Claim 8
Dependent Claim 34 words
The disk drive enclosure according to claim 2, in which: said viscoelastic material having a pressure sensitive adhesive coating is a pressure sensitive adhesive tape which comprises and energy absorbing material for vibration damping.
Claim 9
Dependent Claim 23 words
The disk drive enclosure according to claim 7, in which: said energy absorbing material comprises a soft, deformable thin film on said tape.
Claim 10
Dependent Claim 16 words
The disk drive enclosure according to claim 7, in which: said deformable thin film is aluminum.
