    摘要： The digital laser image recorder includes a data manipulation and control system which may provide digital data to a digital light source for conversion to an analog modulated light beam. A scanner may also be provided to direct the light beam toward a writing surface which may be disposed on the interior of a rotatable cylinder. A film handling device operable to deliver sheet film to the writing surface may also deliver sheet film from the writing surface to an associated output tray after writing. In another embodiment, beam shaping optics may be provided to convert the analog modulated light beams to collimated beams of a predetermined size and circular distribution. The beam shaping optics may also incorporate a power control filter to control the intensity of the collimated beams. In yet another embodiment, a shutter may be provided. The shutter may have a reflective surface with a first position in which the shutter reflects the light beams away from the scanner, and a second position in which the light beams strike the scanner. A photodiode may also be provided to measure the intensity of the reflected light beams. In still another embodiment, focusing optics may be provided to focus the collimated beams to form laser beams which may be directed toward the scanner.

    摘要： The optical tape recorder of the present invention is capable of archiving data at rates in excess of 400 megabits per second by concurrently writing or reading a plurality data tracks in each data trace. A read-write module outputs an illumination beam comprised of combined multiple write beams (channels), a read beam and an autofocus beam. Optics within the read-write module spatially combine and accurately position the plurality of beams with respect to each other to form the multi-beam illumination beam. A read-write head comprised of a synchronized scanning transmissive polygon and rotating lens wheel scans the multi-beam illumination beam across a recording media to read or write multi-channel data tracks. An autofocus system is also included to ensure that the multi-beam illumination beam is accurately focused on the recording media.

    摘要： An optical scanning system wherein a moving cylinder supporting a segment of recording media on its inner surface is axially moved over a pair of fixed cylinders. A slit is provided between the fixed cylinders, and a light beam is radially scanned by the system through and along the slit to scan the surface of the supported segment of media as the moving cylinder moves in an axial direction over the fixed cylinders and across the slit. A pressure source provides air to the moving cylinder, with the supplied air expelled from an inner surface of the moving cylinder against the fixed cylinders to form an air bearing. Air is also expelled into the area between the fixed and moving cylinders to float the media therein during media advancement. A vacuum source is also provided to draw air through the moving cylinder from the area between the fixed and moving cylinders holding the media against the inner surface of the moving cylinder while the media is being scanned by the light beam.
