    摘要： An intermediate layer including at least one of elements constituting a phase change material and silicon is arranged between a recording layer composed of the phase change material and an n+ polysilicon film to reduce contact resistance between the recording layer and the n+ polysilicon film, thereby simplifying the structure of a phase change memory and reducing the cost thereof. If the phase change material contains Ge, Sb, and Te, for example, the intermediate layer includes at least one of Si—Sb, Si—Te, and Si—Ge.

    摘要： Recording parameters are decided so that the time control information on at least the front edge and the rear edge of a parameter forming a mark of twice size or above of the laser spot diameter focused on the recording medium is substantially proportional to the recording linear velocity. The mark is recorded and reproduced at a predetermined linear velocity to obtain an electric signal waveform having a time width Tm. A parameter is decided so as to control the laser pulse for recording information so that a voltage value change amount at two points at a distance Ts (Ts

    摘要： Pulses modulated between the erase power and the bottom power are used instead of cooling pulses for an optical disk medium that needs a write strategy with 4-valued power levels. Consequently, pulse instruction lines for the cooling pulses, power level instruction lines, and corresponding current source within the laser driver can be omitted. Decrease in size and lower power consumption can be accomplished.

    摘要： When a super resolution technology for optical disks is used in a situation where optical disk management information is formed with a signal that cannot be reproduced by a reproduction method based on a conventional optical disk technology, optical disk drives cannot make recording adjustments and/or reproduction adjustments. An optical disk drive uses an optical disk that forms a management information signal with pits not smaller in size than optical resolution and can be read by a reproduction method based on a conventional optical disk technology. When the optical disk drive records information onto or reproduces information from the optical disk having the super resolution region, it is possible to make proper recording adjustments or reproduction adjustments and perform a proper recording operation or reproducing operation in an optical disk's information region for user information recording or reproduction.

    摘要： A write type optical disk device with the PRML mode allows accuracy in the trial writing to be improved accompanied with the high speed processing while assuring the readout compatibility. A readout signal that has been A/D converted at timing that interposes the edge has its phase compensated with the even numbered FIR filter. The level at the edge point and the absolute values thereof are accumulated respectively so as to provide a circuit for detecting the edge shift and jitter. Coping with the high speed processing, the edge shift of the readout signal is detected at the position where the edge shift is around zero, thus improving the accuracy in learning of trial writing.
