    摘要: An apparatus for improving the focus of a digital optical record and playback system is described which provides plural simultaneous focal paths of different lengths for playing back or recording a digital optical data record. These focal paths may interact a common bit portion on a data record, successive bit positions in the same row of data on the record, or bit portions on adjacent tracks of data on the record. In certain embodiments, a selection circuit is utilized for evaluating the focal paths and selecting one which results in an improved focus. Data records having recorded bits of data of extended depth are also described to facilitate focusing during playback of the data record.

    摘要: A record and playback system for reducing repetition redundancy is described in which during recording, a partially repetitive signal, such as a television signal, is converted into digital data words each representing the signal occurring during a particular TV line subinterval. A comparator unit receives the data words and compares each received word with a word from a recirculating storage that corresponds to the same line subinterval in its frame as that of the compared received data word. When the compared words differ by a predetermined value, the received word replaces the stored word in the storage and is also stored in a changed data memory as an updated data word along with address words. A recording control circuit intermittently causes the read out of data from the changed data memory for recording at selected positions of a data record. The storage includes alternately operating first and second recirculating storages which each store a set of data words equal in number to the number of data words of one-half a TV frame. Audio data words are stored for recording during vertical blanking intervals of the signal. On playback, a record pickup intermittently reads data words from the record to a record pickup memory whenever this memory is nearly empty. A composite signal generator reconstructs the recorded television signal from data words it receives from the display storage and display control.

    摘要: The effective resolution of a TV presentation reproduced from digitally encoded samples is improved by shifting the sampling points back and forth at a relatively rapid rate. Alternate lines of the original television raster are sampled at shifted points, wherein the shift is less than the sampling interval and suitably one half the sampling interval. Since a TV raster includes an odd number of horizontal lines, a particular line location on the reproduced raster will be formed of samples which shift back and forth at one half the TV frame rate, i.e. 15 cycles per second.

    摘要: A compact optical memory in which data is stored in an optical data layer capable of selectively altering light such as by changeable transmissivity, reflectivity, polarization, and/or phase. The data is illuminated by controllable light sources and an array of multi-surface diffractive imaging lenslets cause a data image to be projected onto an array of light sensors by reflecting, hence folding the image rays, by means of a mirror that both reflects and optically modifies the light rays to redirect them onto the sensor array located substantially coplanar with the data layer. Data is organized into an annular array of patches (called pages). By selective illumination of each data page, one of the lenslets images the selected data page onto a central image plane where the sensor array is located. Light in the data image pattern strikes different ones of the arrayed light sensors, thereby outputting a pattern of binary bits in the form of electrical data signals. By selectively and sequentially illuminating different ones of the data regions (pages) on the data layer, correspondingly different data patterns are imaged by the corresponding lenslets onto the common sensor array, thereby enabling many stored data images to be retrieved by multiplexing at electro-optical speed.

    摘要: A track intercept apparatus is described for use in an optical playback machine which plays back data recorded on an optical record in track segments. The apparatus deflects the scanning light beam of such machine so that the light beam intercepts each selected track segment properly when the scan is initiated. A track intercept control circuit is employed having storage means for storage of variable values of track alignment data, adjust means for producing an adjustment signal corresponding to the stored data which is applied to a light beam deflection means, and timing means for controlling gating circuitry and for coordinating events within the circuit with the operation of the playback machine as a whole. One embodiment of the invention includes a circuit which compensates for track-following corrections made during scanning by returning the scanning light beam to a stored starting position. Another embodiment has a circuit for electronically aligning the scanner optics. A third embodiment includes a circuit for using data track addresses to direct the scanning light beam to the correct track. A fourth embodiment has a circuit which combines the first three embodiments.
