Techniques for preventing electrostatic discharge (ESD) and circuit noise are provided. More particularly, the present invention provides a method to prevent ESD damage during the assembly of computer disk commonly called a hard disk for memory applications. The coating mainly involves a ion-deposition process. Merely by way of example, the present invention is implemented by using filtered cathodic vacuum arc (FCVA) with a dissipative crystalline and/or amorphous carbon base thin film coating on a flexible circuit to drain the potential electrostatic charges during circuit assembly and interconnect processes, yet it would be recognized that the invention has a much broader range of applicability on any electronic apparatus that is susceptible to electrostatic damage and static noise.

A disk drive includes an opaque cover secured to a base, where the opaque cover has an opening. A see-through insert, which includes an electrically conductive material, is affixed to the opaque cover over the opening. The electrically conductive material may be a coating applied to the see-through insert which, in one embodiment is a polymer coating having a certain surface resistivity. Alternatively, the coating's ESD-dissipative properties may be due to the presence of sputtered gold, sputtered indium tin oxide or a metal film. The electrically conductive material may alternatively be embedded in the see-through insert.

When the HDD body and the two conducting frames is installed in a containing room of an electronic device (e.g. notebook computer), the requirements of shock protection, EMI protection and grounding for the HDD body is achieved by virtue of the compression of those elastic projections.

Provided is a buffer member helping to achieve stable electrical connection between a casing of an external storage device and an accommodating portion thereof without involving an increase in the number of components. A buffer member has a conductive connection layer held in contact with a hard disk drive and with an accommodating portion, so it is possible to dissipate static electricity with which the hard disk drive is charged and electromagnetic wave noise through the conductive connection layer to the accommodating portion or a casing of a notebook PC electrically continuous with the accommodating portion. Thus, it is possible to prevent malfunction of the hard disk drive and to correctly operate the notebook PC. Further, there is no need to separately provide a conductive member for conductive connection between the hard disk drive and the accommodating portion, thereby making it possible to avoid an increase in the number of components. Thus, the hard disk drive can be easily incorporated into the accommodating portion.

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.

A docking module for conventional small form factor disk drives provides, in one embodiment, space for two such disk drives embedded in tray loaders, within a standard 3.5 inches halve height floppy bay. The docking module provides hot swappable insertion and removal of tray loaders together with disk drives. The bay is provided within a housing member. A button attached to a lever mechanism disconnects the docking module connector from the tray loader connector and partially pull out the loader when the button is pushed; An EMI shield fixedly coupled to the tray loaders each provide a barrier to electromagnetic interference.

An anti-vibration and anti-EMI frame includes an electrically conductive casing having a plurality of side panels, a front opening and a rear opening for receiving a hard disk drive therein before being fixed in an electronic device. The casing is integrally formed on the side panels with a plurality of outward protruded elastic members, and at the rear opening with a stop plate and two mounting plates. The stop plate prevents the hard disk drive from moving out of the casing via the rear opening thereof; the casing is fixed in the electronic device by threading screws through the mounting plates into the electronic device; and the elastic members on the casing are internally in contact with the electronic device. Therefore, the casing protects the hard disk drive against vibration and shields electromagnetic interference to and from the hard disk drive.
