Patent ID: 8300353

Claim:
A disk drive device comprising: a base housing configured to have conductivity in at least part thereof, said base housing having an inner wall surface; a bearing unit configured to be arranged inside the base housing and to rotatably support a recording disk relative to the base housing; and a drive unit configured to rotationally drive the recording disk supported by the bearing unit, wherein the bearing unit includes: a conductive rotating body configured to support the recording disk; a conductive resin housing configured to surround at least part of the rotating body to support the rotating body and to be able to conduct electricity to the recording disk via the rotating body, said conductive resin housing being fixed to said inner wall surface of said base housing by a non-conductive adhesive; and a conductive adhesive applied between the conductive resin housing and the base housing to secure conduction between the conductive resin housing and the base housing, wherein the conductive resin housing has an exposed portion adjacent to said base housing and not covered by said non-conductive adhesive but covered by the conductive adhesive, and wherein the exposed portion is coated with the conductive adhesive to secure conduction between the conductive resin housing and the base housing.
