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.

摘要： A phase change type optical disk includes a transparent substrate, a recording layer, a first transparent protection layer, a reflective layer, and a transparent interference layer. The recording layer is formed above the transparent substrate to cause a reversible phase change between a crystalline state and an amorphous state. The recording layer causes a phase change upon being irradiated with a laser beam, thereby recording, reproducing, and erasing information. The first transparent protection layer is formed on the recording layer to protect the recording layer. The reflective layer is formed above the recording layer to reflect light transmitted through the recording layer and causes the reflected light to be incident on the recording layer. The transparent interference layer is formed between the first protection layer and the reflective layer to cause light beams reflected by the reflective layer to optically interfere with each other. Light transmitted through the recording layer is multiple-reflected between the reflective layer and an interface between the interference layer and the first protection layer.

摘要： The optical phase difference between reflected laser light from the crystalline and the amorphous part of a phase change recording layer is established as 180 degrees .+-.5 degrees. The ratio between the light absorption factor when the phase change recording film is in the crystalline condition to that when it is in the amorphous condition is set to within the range 0.9 to 1.1. With the wavelength of the laser light used as .lambda., the optical depth of a guide groove formed on the substrate is set to within the range .lambda./9 to .lambda./6. With the wavelength of the laser light used in the range 635 nm to 650 nm, the depth of the guide groove is in the range 40 to 70 nm. In an optical disk such as this, when seen from reflected light, the groove region of a groove during playback and land region of the groove during playback are optically equivalent. For this reason, it is substantially the same as the case in which the optical phase difference between the reflected laser light from the crystalline part of the recording film and the reflected laser light from the amorphous part of the recording film is zero, this making it possible to achieve consistency in the signal levels between land playback and groove playback. As a result, it is possible to perform double track density recording and mark edge recording.

摘要： The optical disk writing system disclosed is one in which a data written on an optical data writing medium is verified essentially simultaneously with the writing on the medium. The written data is verified by detecting a timing of the light irradiated on the medium and by measuring return light doses at a rise and a fall of the light irradiated on the medium and comparing the doses thereof with predetermined reference values. The medium used is one which uses a phase transition reversible between a crystal state and an amorphous state for writing/reading/erasing of data on a data writing film and includes, a first protective film, a phase transition type data writing film, a second protective film, a reflection film formed in this order on a transparent substrate. The thickness of the first protective film is set such that, of three reflectivities of the data writing film respectively in crystal, amorphous and melted states, the reflectivity in the crystal state and the reflectivity in the melted state are made different from each other, and the reflectivity in the amorphous state and the reflectivity in the melted state are made different from each other. A high speed writing operation can be carried out and an overwrite operation can be completed in one time disk rotation.
