摘要： PROBLEM TO BE SOLVED: To provide a recording medium capable of stably reproducing binary information recorded in advance in its innermost circumference area. SOLUTION: The recording medium is formed by laminating a first information layer 2, an intermediate layer 3, a second information layer 4 and a cover layer 5 sequentially on a substrate 1. A first groove is formed in advance in a first area 11 of the substrate 1, and a second groove is formed in advance in a second area 13. The first groove is set shallower or narrower than the second groove. As a result, the signal recorded in the first area 11 of the substrate 1 can be less modulated by the diffraction of the first groove. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To form the groove of a narrow width and to increase the density for a disk. SOLUTION: A laser beam is intensity-modulated by an EOM 2 and made incident on a modulation optical system 5. Even when a linear velocity is changed in a radial direction by an APC 4, the optical output of the laser beam transmitted through the EOM 2 is stabilized. A light beam is converged to an AOM 6 and the light beam is modulated by DC signals and pit signals. The AOM 6 is controlled so as to change the optical output linearly and separately for a pit and the groove. An exposure beam emitted from the modulation optical system 5 is made incident on an AOD 10, optically deflected, led through a mirror M2, a polarizing beam splitter PBS, a lens L3 and a mirror M3 to an objective lens 14 and converged on a photoresist film 16 by the objective lens 14.

摘要： PROBLEM TO BE SOLVED: To enhance the recording density of a recording medium to have equal to or higher than a resolving power to be determined with the wavelength of reproducing light by impressing a magnetic field to a magnetic recording medium so that magnetization is directed in a fixed direction in the region of one part in the spot of reproducing light when an information signal is reproduced by irradiating the medium with the reproducing light. SOLUTION: When a magneto-optical disk is irradiated with reproducing light La from the side of a reproducing layer 4a of the disk and also a reproducing magnetic field Hr is impressed on the a region icluding the spot S of the reproducing light by the reproducing light La while rotatingly driving the disk, the reproducing layer 4a of a low temp. region B1 is initialized by the reproducing magnetic field Hr and the magnetization of the reproducing layer 4a of the low temp. region B1 is always directed to a fixed direction regardless of the magnetization direction of a recording state holding layer 4c and, as a result, the low temp. region B1 becomes a so-called front mask by masking the front side of the scanning direction of the spot S of the reproducing light. In a high temp. region B2, magnetism of an intermediate layer 4b disappeares and an exchange coupling in a recording layer is cut and the reproducing layer 4a is always magnetized in the direction of the reproducing magnetic field Hr.
