摘要： A reflectance increasing type optical information recording medium in which the crosstalk is inhibited in the land and groove recording. This optical information recording medium comprises a substrate having a groove and a land provided between adjacent grooves and a recording layer that is provided on the substrate and that changes the reflectance by irradiation with light beams. In this recording medium, the reflectance after recording is greater than the reflectance before recording. Moreover, the depth D of the groove is set to be in the range of &lgr;/8n to 3&lgr;/8n, where the wavelength of the light beam is &lgr; and the refractive index of the substrate is n. And the difference, &Dgr;&phgr;=&phgr;1−&phgr;0, between the phase &phgr;1 of the reflected light after recording and the phase &phgr;0 of the reflected light before recording is in the range of (−0.1+2 m) &pgr; to (0.1+2 m) &pgr;, where m is an integer.

摘要： On a substrate, a recording layer which reversibly transforms between two states with different optical properties--a crystalline phase and an amorphous phase--by the irradiation of a laser beam, a first and a second dielectric layer on the bottom and the top surfaces of the recording layer, and a third dielectric layer on one surface of the first or the second dielectric layers and on the opposite side with respect to the recording layer are successively laminated, thus preparing an optical information recording medium. The third dielectric layer has a smaller coefficient of thermal expansion than the first and the second dielectric layers, so that the thermal deformation of the first and the second dielectric layers is reduced and the mass transfer of the recording layer is controlled. As a result, the overwrite cycle characteristics of the optical information recording medium are excellent.

摘要： Tracking control is carried out by a push-pull method or by mechanical feed at the time of recording signals, and tracking control is carried out by a phase difference tracking method at the time of reproduction. Thus, a phase change type optical disk which enables phase difference reproduction and is erasable may be realized. In a phase change type optical disk having a phase difference reproduction structure, servo mechanism at the time of reproducing signals may be stably controlled by causing the reflectance of a blank portion to be higher than the reflectance of a recording mark portion.
