摘要： When there is a defect area in a specific recording layer, recording of information is continued and reduction in a recording rate is restrained. In an optical recording method for recording information on a multilayer optical recording medium having a plurality of recording layers by irradiating the recording layer with a beam spot, any recording layer is set as an escape recording layer. When a defect area is detected while information is recorded on another recording layer except for the escape recording layer, the beam spot moves to the escape recording layer to continue recording the information.

摘要： A method is provided to enable efficient optimization of write pulse waveforms using a trial writing region. To record information on an optical recording medium using a laser beam, the method includes: recording a specific pattern of multiple record marks on the trial writing region of the optical recording medium; decoding a read signal from the specific pattern using a PRML detection method; and tuning a write pulse waveform for forming the record marks based on the quality of decoded data determined by the PRML detection method.

摘要： When the recording capacity of an optical recording medium is increased, both reproduction characteristics and a tilt margin are improved. Specifically, when a laser beam is projected onto an information recording layer of the optical recording medium to reproduce information, a laser beam having a wavelength of 400 to 410 nm is employed. In addition, an objective lens which converges the laser beam and has a numerical aperture NA of 0.70 to 0.90 is employed. The reproduction is started by projecting the laser beam. A reproduction signal obtained by projecting the laser beam is decoded by means of a PRML detection method to generate reproduction data of the optical recording medium. When the quality of the reproduction data deteriorates, the power of the laser beam is temporarily increased.
