Hard disk drive with electrically conductive sheet for electrostatic discharge protection

A hard disk drive has an enclosure with disk construction members and is characterized by covering the enclosure with an electrically conductive sheet. The electrically conductive sheet protects the drive regardless of which direction an ESD charge is applied. The electrically conductive sheet does not permit ESD to pass through the disk construction members stored in the enclosure. Therefore, it is possible to form a structure in which a GMR head or the like in an enclosure is not damaged due to ESD even if the enclosure is handled by a general end user. Moreover, the present invention relates to an electrically conductive sheet for covering at least both principal planes of the enclosure of a hard disk drive constituted as described above. Other modes of the invention include at least both principal planes of an enclosure being covered by the electrically conductive sheet in such a way that both sheets on both principal planes are electrically connected. In addition, portions where the enclosure contacts the disk construction members on both principal planes may also be covered and electrically interconnected. Furthermore, the electrically conductive sheet may be bonded to the surface of the enclosure by an adhesive, or provided with an opening at a position corresponding to an enclosure portion that must be brought into contact with an external atmosphere.
