摘要： It is to provide an optical disc recording apparatus and a recording power control method that are adapted to high-speed recording and can set an optimal erasing power with high accuracy. A test writing signal detector reproduces a test writing signal of a predetermined mark length or space length with varied power, and detects the number of error mark signals and an amplitude value of an envelope. A controller obtains a first threshold Pe0 of the erasing power based on the number of error mark signals in a region where laser power is low, and obtains a second threshold Pe1 of the erasing power based on the amplitude value in a region where the laser power is high. Then, the controller sets an optimal value of the erasing power from an average value of the first and second thresholds.

摘要： Means is provided that produces stabilized trial write results when, for example, servo misalignments are caused due to deviations on an optical disc that requires trial writes at high linear velocity. A recording method produces a recording parameter in the event of recording information into an arbitrary address position in the manner that a recording parameter is obtained through a predetermined calculation method from the results of learning of recording parameters on two or more zones of the optical disc where the linear velocities are different form one another. In a zone where the linear velocity is low, the method determines an optimal recording parameter from a jitter value of a reproduced signal waveform generated in a trial write. In a zone where the linear velocity is high, the method determines an optimal recording parameter in accordance with information obtainable from an amplitude value of a reproduced signal generated in a trial write.

摘要： An optical disk apparatus and a recording parameters setting method are provided to more effectively execute recording parameter learning during data recording on the optical disk, thereby shortening the time required for setting an optimum recording parameter. A phase error detection unit detects a phase error amount from a reproduction signal of actual data being recorded. A phase error adjustment unit adjusts recording parameters (recording strategy) set by a recording parameters setting unit based on the detected phase error amount. The phase error amount detection is executed simultaneously with a verify process of the actual data. If a verify process judgment results says that a target quality is not attained, test writing by a test signal is not executed but the adjustment of recording parameters is conducted on the basis of the phase error amount.
