摘要： The present invention relates to a recording and reproducing method and apparatus for an optical disk of the phase transition type that can be overwritten. According to this invention, the capacity of repeated rewriting of the optical disk is expanded by recording either non-inverted write data or inverted write data at random. The deterioration due to the repeated rewriting at a start point and an end point of the recording is suppressed by recording a synchronizing signal before the write data and/or dummy data after the write data in the way such that thermal stress is less likely to occur. A record end position can be determined precisely by detecting a stop pulse to stop recording.

摘要： A recording and reproducing method and apparatus for an optical disk of the phase transition type is provided. This method comprises the steps of deciding at random to invert or not to invert write data that has a predetermined block length; inverting the write data if the decision is to invert the write data; and recording either the non-inverted write data or the inverted write data into the photo-sensitive record layer. A synchronizing signal is recorded before the write data and/or dummy data after the write data in the way such that thermal stress is less likely to occur. A record end position can be determined precisely by detecting a stop pulse.

摘要： A recording and reproducing apparatus for an optical disk of the transitional type that can be overwritten, having an optical information recording medium. The medium has a guide groove and a sector ID area. Information is recorded by irradiation with a light beam to change a state of a photo-sensitive record layer, and the recording may be stopped by the generation of a stop pulse. The stop pulse may be generated by an altered width of the guide groove before the sector ID area, or by one or more larger prepits before the sector ID area.

摘要： A method of manufacturing an optical information recording medium comprising the steps of: forming a plurality of component thin films on a substrate or on a sample at a predetermined film-forming speed and within a predetermined film-forming time in sequence; measuring spectral reflectance of the multilayer thin film formed on the substrate or on the sample; comparing the measured value of the spectral reflectance and the standard value of the spectral reflectance to detect the difference between them; compensating at least one of the film-forming speed and the film-forming time based on the detected difference; and forming a plurality of thin films based on the compensated film-forming speed and with the compensated film-forming time. Consequently, a thickness of each component thin film of the optical information recording medium can be measured easily and production loss in measuring a film-forming speed can be decreased.

摘要： An optical recording medium includes a main-information area in which a metal reflection film is formed on a substrate where a row of pits is formed as main data, and a sub-information area in which is recorded medium identification information, which is used to identify the optical recording medium individually, by removing the metal reflection film partially and forming a plurality of reflection-film removed areas. Information is reproduced by irradiating the metal reflection film with a beam of light. In the sub-information area, a row of pits or a guide groove is formed on the substrate, and a track pitch of the row of pits or the guide groove is at least 0.24 μm wide and at most 0.45 μm wide.
