摘要： A thermomagnetic recording method is disclosed using a thermomagnetic recording medium where first, second and third magnetic thin films each formed of rare-earth and transition metals are sequentially superposed to form layers in a magnetically coupled manner. The recording is carried out by heating the thermomagnetic recording medium under a predetermined magnetic field perpendicular to the film plane thereof while selectively modulating, in accordance with data to be recorded, a first heating state at a first temperature T1 substantially above the Curie point Tc1 of the first magnetic thin film and adequate to hold the sublattice magnetization of the transition metal of the second magnetic thin film in a predetermined direction, and a second heating state at a second temperature T2 substantially above the Curie point Tc1 and adequate to invert the sublattice magnetization of the transition metal of the second magnetic thin film to the reverse of the predetermined direction. In a cooling step subsequent to the first and second heating states, maintaining the sublattice magnetization of the third magnetic thin film in a predetermined direction while orienting the sublattice magnetization of said second magnetic thin film to be directionally coincident with that of the third magnetic thin film at a temperature below the first temperature T1 without directionally inverting the sublattice magnetization of the first magnetic thin film.

摘要： An optical recording medium illuminated by light from a light source as near-field light using a focusing lens whose numerical aperture exceeds 1 to perform recording and/or reproduction is provided, wherein a composite layer in which a high refractive index material portion having a refractive index higher than that of a light-transmissible material portion is mixed in the light-transmissible material portion is provided on the surface of a light incident side of the optical recording medium. With an average refractive index of the composite layer being high, a numerical aperture controlled by a refractive index of a surface layer can be made large to obtain higher resolution and higher durability against contact with a lens or the like.

摘要： The present invention relates to an optical disc on which an information signal can be rewritten. Guide grooves (81a) for tracking control are formed on respective tracks of the rewritable area where an information signal can be rewritten. A recording layer (83) onto which an information signal is to be written is laminated on a substrate on which the guide grooves (81a) have been formed. The information signal can be rewritten on the recording layer (83) at least in the rewritable area using near-field light based on multibeam. Concave portions (85a) are formed on the outermost surface of the disc recording medium in correspondence with the positions of the guide grooves (81a).
