    摘要: Fabrication of an MO disc, the formation of a master pattern of servo and track information, and the subsequent transfer of that pattern to a series of pits and grooves on a substrate. On top of that substrate, at least one sacrificial layer is provided atop a relatively hard layer. The recording stack may be provided with both silicon nitride and silicon dioxide top layers, with the silicon dioxide layer acting as a sacrificial layer to ensure that the hard layer, of silicon nitride, remains at the end of the process. A layer of aluminum or aluminum alloy may be deposited, with the aluminum plugs filling the grooves and pits (created by the embossed servo information) to a level higher than any of the adjacent layers of silicon dioxide, silicon nitride, or similar dielectric layer. Since the polishing rate of aluminum can be far faster than that of the silicon dioxide, then the aluminum can be etched or otherwise removed down to a level equal to or slightly below a planar surface with the silicon dioxide, with the silicon dioxide layer allowing for some small level of over polishing. The silicon nitride layer is protected completely; the silicon dioxide layer partially remains and is partially removed; and the aluminum metal which fills the grooves and pits would rise only to a level substantially equal the very flat top surface of the silicon dioxide.

    摘要: A data storage system including a source of heat, a substrate, a storage layer, a lubricant layer, a flying head, and a dielectric layer is disclosed. The dielectric layer is disposed between the lubricant layer and the storage layer. The flying head is disposed above the lubricant layer. The dielectric layer has a heat capacity that is sufficient to generate a temperature gradient between the storage layer and the lubricant layer so as to reduce lubricant evaporation onto the flying head.

    摘要: A positioning system for selectively directing a first beam of light towards a destination and a second beam of light towards a first diffractive optic. The first beam of light and the second beam of light traverse a substantially co-linear optical path. The first diffractive optic diffracts the second beam of light into a plurality of optical spots. The second beam of light comprising the plurality of optical spots is directed onto a second diffractive optic. A change in position of the plurality of optical spots relative to the second diffractive optic is sensed in a reflection of the second beam of light by a detection element and representative signals are derived thereof. The signals are coupled to a directing assembly, which directs the first beam of light towards the destination.

    摘要: A diode-laser bar package includes a diamond composite heat-sink on which is soft-solder bonded a copper-pad having an area much greater than that of the diode-laser bar. A constraining-block of a metal having a CTE matching that of the diode-laser bar is hard-solder bonded to the conductive pad. The constraining-block is configured such that the conductive pad in the region of the diode-laser bar has a CTE about equal to that of the constraining-block, and, accordingly, the diode-laser bar.

    摘要: A laser printer arranged to print a pixellated image on laser sensitive tape includes a carriage on which are arranged two laser-beam sources delivering separately modulated laser-beams and optics for focusing the beams on the tape. The tape is mounted on a tape drive which drives the tape incrementally in one direction. The carriage is translated over the tape in a direction perpendicular to the tape-drive direction, while the modulated beams are focused. Two rows of the pixellated image are drawn across the tape in this manner. The tape is then incremented and a further two rows are drawn.

    摘要: A balanced microdevice comprising a substrate, a movable structure overlying the substrate, an element and a lever assembly having a pivot and a lever coupled to and pivotable about the pivot. The lever has a first extremity coupled to the movable structure and an opposite second extremity coupled to the element. The movable structure causes the lever to pivot about the pivot so as to move the element in a direction of travel. The element is substantially mechanically balanced to inhibit undesirable movement of the element in the direction of travel in response to externally applied forces.

    摘要: Micro-machined tools and component holders useful for the manufacture, assembly, and testing of precision micro-miniature parts are provided, particurlarly embodiments well adapted for precision micro-miniature systems incorporating optical and/or electronic components including lenses, optical fibers, and the like. Structure and method find particular applicability in the precision optical systems of the read, write, or read/write heads of optically assisted storage devices for digital computers. Removable tools are used to temporarily position components while the components are glued or otherwise fixed into place during assembly, and then completely removed for use with another head assembly. Break-away tools or holders typically include three major portions: an element holder, a handle, and a break-away neck portion connecting the holder with the handle. The element holder provides a mounting block for an optical, electrical, or mechanical element. Once the elements are attached to the mounting blocks, they are moved into position within the larger assembly via the handle, the mounting block is glued to the assembly and a small predictable force is applied to the handle to break the neck and separate the handle from the holder which is at that time attached to the assembly. Tools may be formed by photolithographically patterened and etching a substrate such as silicon to selectively carve the substrate. Structures formed from plated metal, either on a base material, or made entirely of metal are also provided by the invention. Several embodiments of process for forming the inventive structures are also provided.
