    • Information to be recorded is recorded in a recording layer of a phase-change optical storage medium. The information to be recorded is modulated to generate modulated data. Desired mark-length data is generated based on the modulated data. Generated further based on the mark-length data is a recording pulse pattern of recording pulses rising from an erasing power and formed between a recording power larger than the erasing power and a bottom power smaller than the erasing power and of erasing pulses rising from the bottom power to the erasing power. A recording light beam is then irradiated onto the recording layer in accordance with the recording pulse pattern to record at least one recorded mark representing the information to be recorded. Used in recording is an optimum erasing power, as the erasing power, the optimum erasing power satisfying an expression (1): 1.000

    • First identification data and second identification data are read out from a phase-change optical storage medium having a light-incident surface through which a light beam is to be incident and at least a first film-laminated layer structure and a second film-laminated layer structure provided over the surface in which the first structure is provided as closer to the surface than the second structure is. Each structure has at least a recording film. The data indicates first recording requirements to the first structure. The second data indicates second recording requirements to the second structure. The first and second requirements are different from each other. Given data to be recorded is modulated into modulated data. A data-recording signal having at least one mark followed by a space is generated based on the modulated data. The mark has a mark length nT (“T” being a unit dock cycle, and “n” being a positive integer of 3 or larger but 14 or smaller). Recording is controlled as to whether to record the data to the first or the second structure based on the first and second data. A first recording pulse sequence is generated based on the first requirements when the controller controls recording so that the data is recorded to the first structure. A second recording pulse sequence is generated based on the second requirements when the controller controls recording so that the data is recorded to the second structure. The first sequence has an (n−1)-number of recording pulses with a power corresponding to the mark length nT and additional pulses with a power that are generated for a period of the space and follow the recording pulses. The second sequence has an n/2-number of recording pulses with a corresponding to the mark length nT when “n” is an even number whereas having an (n−1)/2-number of recording pulses with a power corresponding to the mark length nT when “n” is an odd number. The data is recorded to the first and second structures with the light beam driven with the first and second sequences, respectively.

    • 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.
