  • Patent number: 4879691
    Abstract: An optical recording medium which has data tracks and tracking lines juxtaposed with each other in a data recording region so as to write/read data into/from the data tracks, using the tracking lines as a reference. The data recording region is so configured as to have recessed portions and raised portions arranged alternatingly and extending along each other in a direction of data reading/writing. The so formed recessed portions and raised portions provide data tracks. With this configuration, the boundary edges between the respective recessed portions and the respective raised portions are used as tracking lines, so that data can be written in the recessed or raised portions, referring to the boundary edges as tracking lines.

  • Patent number: 4831609
    Abstract: A tracking method for reading/writing data with respect to an optical recording medium having clock tracks each formed of clock bits of optical patterns and data tracks. The method is carried out by irradiating from an optical lead side a pair of light beams onto a pair of clock tracks, with the beams so deviated from each other in a direction of relative movement of the optical head with respect to the medium that beam detection signals may have a difference in phase therebetween. Reflections of the respective light beams from the clock tracks are detected and a difference signal between reflections determined from the detection signals is obtained. A tracking-error signal from the difference signal is extracted and a zero-crossing point of the difference signal then is detected to extract a clock signal.

  • Patent number: 4794244
    Abstract: A method and apparatus for detecting a focussing position wherein a difference between photoelectric outputs from two photodetectors is amplified by a differential amplifier to detect a deviation of a focal point of a reader/writer head in the reading/writing operation for an optical recording medium.Prior to the amplification of the difference between the photoelectric outputs from the photodetectors, the output voltage from one of the photodetectors is changed to be input to the differential amplifier and the changing ratio is set so that the output from the differential amplifier will be zero when focalized.For this purpose, a voltage changing device for changing the photoelectric output from the photodetector is provided between an output of the photodetector and an input of the differential amplifier.
