摘要： Data is recorded in an optical storage medium with a beam having a wavelength in a 650-nm band. The medium has a substrate, a first laminated layer structure formed on the substrate and having at least a first reflective film and a first recording film, and a second laminated layer structure formed over the first structure and having at least a second reflective film and a second recording film. The data is recorded in at least one of specific sections of the first recording film, with a beam having a wavelength in a 650-nm band and a beam spot having a specific area. The first structure satisfies requirements Tc≦Tr≦60% and 9%≦Rr≦Rc≦15% wherein Tc and Rc are a transmissivity and a reflectivity, respectively, of the first structure when the first recording film has no data recorded therein after initialized, and Tr and Rr are a transmissivity and a reflectivity, respectively, of the first structure when the first recording film has the data recorded therein. The transmissivity Tc and the reflectivity Rc, and the transmissivity Tr and the reflectivity Rr are exhibited by the first structure when the beam is emitted thereto through the substrate as a parallel beam having a sectional area in a direction orthogonal to another direction in which the beam travels. The sectional area is larger than the specific area. Data is recorded in the second recording film through the substrate and the data-recorded specific section of the first recording film. The second structure exhibits a reflectivity of 5% or higher but 10% or lower when the beam is focused onto the second recording film, as having the beam spot having the specific area, through the substrate and the first structure, and when the first recording film has the data recorded therein.

A second recording pulse sequence is generated for recording to a second data layer. The second sequence has recording pulse carrying an erasing power and a recording power rising from the erasing power, a cooling puse carrying a bottom power lower than the erasing power, and an erasing top pulse carrying an erasing top power higher than the erasing power.
