  • Disk drive cover having a see-through insert including an electrically conductive material
    Patent number: 7605999
    Abstract: 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.

  • Apparatuses and methods for directing light beams in an optical recording system
    Patent number: 6724711
    Abstract: A rotatable optical wedge rotatable between a first position and a second position in an optical recording system directs a light beam to a position on a recording medium. The position of the incident light beam is adjustable by moving the optical wedge to different positions, including the first and second positions.

  • Fast response micro-modulator arrays
    Patent number: 6525867
    Abstract: Micro fabricated arrays of optical modulators of both a surface electrode and machined mesa nature where the small structure size and low capacitance electrical connections permit each modulator element to be individually electrically addressed thus providing modulator optical rise and fall response times in the low and sub nanosecond range. Both sparsely spaced and closely packed arrays are achieved.

  • Apparatuses and methods for reading after writing in optical recording systems
    Patent number: 6483797
    Abstract: A read-after-write system for optical recording systems includes a mirror used to direct read beams to a desired position on a recording medium relative to write beams impinging on the recording medium. The mirror may be adjustable to direct the read beams through a range of possible positions.
