摘要： An optical recording and reproducing method is able to record and reproduce information by using an optical system using recording and reproducing light with a wavelength selected in a range of from 780 nm±10 nm and an objective lens with a numerical aperture NA selected in a range of from 0.45±0.01 and records and reproduces first and second optical recording mediums having different recording capacities. The first optical recording medium is constructed by using a substrate with a track pitch Tp1 being selected in a range of from 1.5 μm to 1.7 μm and a groove depth d1 being selected in a range of from 70 nm to 90 nm, and the second optical recording medium is constructed by using a substrate 11 with a track pitch Tp2 being selected in a range of from 1.2 μm to 1.3 μm and a groove depth d2 of the groove 12 being selected in a range of from 150 nm to 180 nm. This, the optical recording medium has compatibility with existing optical discs and has a recording density high enough to record a moving picture.

摘要： A magneto-optical recording medium includes a first magnetic layer (reproduction layer), a second magnetic layer (control layer), a third magnetic layer (blocking layer), and a fourth magnetic layer (recording layer) having respective Curie temperatures TC1, TC2, TC3 and TC4. The Curie temperatures of the layers satisfy the relationships TC1>TC3>TC2 and TC4>TC3. In addition, the magnetic anisotropy of the third magnetic layer Ku3 is greater than that of the second magnetic layer Ku2. A magnetic domain wall in the first magnetic layer in front of the spot irradiated by the reproduction light in the direction of travel is displaced toward the peak temperature portion so that a recorded domain is expanded. Displacement in the spot direction of a domain wall in the first magnetic layer behind the reproduction light spot in the direction of travel is suppressed. The second and third magnetic layers control the magnetic exchange coupling between the first and fourth magnetic layers.
