Abstract:
An improved method of optically writing and/or reading high density involves: (1) predeterminedly positioning a flat, uniformly thick, flexible, optical disc with respect to an axis of rotation; (2) rotating the disc on such axis at a high speed and in a predeterminedly spaced relation to a predeterminedly shaped, smooth, featureless reference surface and (3) coupling a central region between the disc and reference surface to an ambient gas source. Related apparatus and disc configurations, including embodiments having flexible disc covers, also are disclosed.
An optical disc of the type having a thermally deformable recording layer overlying a reflectively surfaced support features a crenelated disc support surface having grooves of predetermined depth and interleaved lands arranged in a spiral or concentric pattern. The recording layer's outer surface is nominally planar so that the differences in thickness between "over-land" and "over-groove" portions thereof impart high phase-shift contrast to light of a given read wavelength.

346 11
Abstract:
A recording element adapted for real-time writing and reading with light of a single given wave-length utilizes a recording stratum, including a heat-deformable dye-binder layer, overlying a reflective support and is characterized by the dye-binder layer having optical constants such that its reflectance versus thickness variation curve has a first reflectance minimum having a high depth of modulation and the recording stratum having a nominal thickness sufficiently greater than the thickness corresponding to the first reflectance minimum to effect reflection of a significant portion of light of such given wavelength.
Hard Copy Reproduction From Video Disc Information

International Classification:
H04N 126
US Classification:
3581286
Abstract:
Facsimile recording on a video disc, wherein a document such as a bank check is recorded as a frame of video information, generally requires that the frame of recorded information be displayed or transformed into a hard copy reproduction of the original document. In accordance with a presently preferred embodiment of the invention, the frame of video information is recorded on a video disc as two fields of interlaced lines recorded on adjacent circular tracks. Upon playback, the circular tracks are alternately read to produce the customary video display of two interlaced fields. To provide a hard copy reproduction of the original document, the circular tracks are simultaneously read and the resultant signal fed to a signal processing circuit. The output of the signal processing circuit comprises, in alternation, lines of video information from each field. This output signal is fed to a printer device which prints, line-by-line, a hard copy reproduction of the original document.

Method Of Providing Close Contact For Contact Printing

International Classification:
G03C 506 G03C 504
US Classification:
430396
Abstract:
In certain types of printing applications (for example optical or magnetic contact printing) wherein it is desired to transfer imagery from a master device to a replicate device, providing and maintaining close contact between the master device and the replicate device poses certain problems. These problems become even more acute if the surfaces to be contacted are of large area. In accordance with the present invention, close contact over even large areas is obtained between a master device and a replicate device by forming a thin and uniform liquid layer between the master and replicate devices, thus producing a vacuum effect which serves to tightly press the master and replicate devices together.
Optical Configurations For A Rotating Polygon Film Scanner
Optical configurations for a rotating polygon film scanner for scanning film such as motion picture film or slide transparencies to produce a television signal are disclosed. The film scanner includes a solid-state line sensing array for scanning the image of a film frame in a direction generally perpendicular to the length of the film, and a rotating multifacet mirror such as a reflecting polygon for displacing the image relative to the line sensing array in a direction generally parallel with the length of the film. The optical configurations include the polygon mirror, a film gate, and a scan lens for forming an image of the film in the gate on the solid-state line sensing array. The scan lens is located between the line sensing array and the polygon mirror to provide on-axis scanning in the direction parallel with the length of the film. The film gate is configured to constrain the film to a surface such that the portion of the image impinging on the line sensing array is always in focus as the image is displaced by the polygon mirror.

Abstract:
Channel encoded data (for example run length limited encoded data) is further encoded in accordance with a shift correction code prior to transmission. Upon reception, forward and backward shift errors present in the received channel encoded data are corrected by a shift correction decoder. The shift error correction is accomplished using a code, such as (for example) a BCH code over GF(p) or a negacyclic code, which treats each received symbol as a vector having p states. For a single shift error correction, p=3 and there are three states (forward shift, backward shift, no shift). In one embodiment, conventional error correction codewords which encode the user data may be interleaved within successive shift correction codewords prior to channel encoding, thereby enabling the error correction system to easily handle a high rate of randomly distributed shift errors (which otherwise would result in a high rate of short error bursts that exceed the capacity of the block error correction code).
