摘要： An optical recording device for use in a recording/reproducing operation has a photodetector for receiving a part of a laser beam generated by a laser source, and a CCD sensor for receiving the laser beam reflected from an optical disk and including information of the energy profile of the laser beam on the optical disk. The signal processor generates a defect signal representing an occurrence of a defect caused by the fluctuation of the laser power and/or the focal position and the cause of the defect during operation of the optical recording device.

摘要： There is disclosed an optical information recording medium having phase-change recording films whose the transmittance can be made substantially uniform irrespective of the presence or absence of recording. There are also disclosed methods for recording, reading, and erasing information well at a high density on such a medium. Each of the phase-change recording films other than the top one has a phase-change recording film for recording and erasing information by a phase change caused by illumination of laser light. A transparent upper protective film is formed on the phase-change recording film to protect the phase-change recording film mainly against thermal deformation during recording and erasing of information. A transparent lower protective film is formed under the phase-change recording film to protect the phase-change recording film mainly against thermal deformation during recording and erasing of information. A foundation interference film is formed under the transparent lower protective film to adjust the transmittance of the phase-change recording film for the laser light.
