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.

What is claimed is: 1. A disk drive comprising: a base; a spindle motor attached to the base; a disk mounted to the spindle motor, and having an axis of rotation about said spindle motor; an actuator attached to the base and having a pivot, said actuator having a head attached thereto for reading data from said disk; an opaque cover secured to the base, the opaque cover including an opening; and a see-through insert including an electrically conductive material, and being affixed to the opaque cover over the opening. 2. The disk drive of claim 1, wherein said opaque cover has a first thermal expansion coefficient that is substantially the same as a second thermal expansion coefficient for said see-through insert. 3. The disk drive of claim 2, further comprising a conductive label affixed to the see-through insert with a conductive adhesive. 4. The disk drive of claim 2, wherein said see-through insert is rigidly affixed to the opaque cover over the opening with a conductive adhesive. 5. The disk drive of claim 4, wherein the see-through insert overlays at least the spindle motor, and wherein said spindle motor is secured to the see-through insert. 6. The disk drive of claim 1, wherein the opaque cover has a first thermal expansion coefficient that is substantially different than a second thermal expansion coefficient of said see-through insert. 7. The disk drive of claim 6, wherein the see-through insert is affixed to the opaque cover with a compliant adhesive. 8. The disk drive of claim 7, wherein the compliant adhesive is a compliant conductive adhesive. 9. The disk drive of claim 6, further comprising a conductive label affixed to the see-through insert with a conductive adhesive. 10. The disk drive of claim 9, wherein the see-through insert has a foam gasket fixedly in contact with the opaque cover. 11. The disk drive of claim 6, wherein said spindle motor is cantilevered, and said see-through insert overlays at least said cantilevered spindle motor. 12. The disk drive of claim 6, wherein the spindle motor is affixed to the opaque cover and the see-through insert partially overlays the disk. 13. The disk drive of claim 1, wherein said opaque cover overlays said actuator pivot. 14. The disk drive of claim 1, wherein said see-through insert is manufactured from a material selected from the list consisting of: polycarbonate, glass, acrylic, ceramic and quartz. 15. The disk drive of claim 1, wherein said electrically conductive material is a polymer coating having a surface resistivity of between about 0.1 to about 30 Mega-Ohms. 16. The disk drive of claim 1, wherein said electrically conductive material is a coating. 17. The disk drive of claim 16, wherein the coating includes a material selected from the list consisting of sputtered gold, sputtered indium tin oxide, and metal film. 18. The disk drive of claim 1, wherein said electrically conductive material is embedded in the see-through insert. 19. The disk drive of claim 18, wherein said electrically conductive material includes a material selected from the list consisting of carbon nanotubes and a metallic material.
