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： The present invention makes it possible to reproduce reproduction images without a break without having to use any additional identification information even when real-time recorded data is not completely continuous. A control circuit references a data identification flag (“Recording Type”) which is attached to each sector of reproduction data to indicate the type of recorded data, and counts the number of sectors to which the data identification flag representing real-time recorded data is attached. When the count is not smaller than a threshold value, the control circuit reproduces all the sectors of the target reproduction block in a real-time reproduction mode. In the real-time reproduction mode, the control circuit masks a portion of reproduction data that is found to be defective, changes the value of the defective data to 0 (zero), and transfers the resulting reproduction data to a host device.

摘要： In the present invention, the processing sequence of a microprocessor for restructuring the recording parameters when changing the recording in an optical disk recording apparatus from a constant angular velocity (CAV) mode to a constant linear velocity (CLV) mode is as follows: (1) interrupt the recording process; (2) calculate a linear velocity at a point where the recording linear velocity becomes constant; (3) calculate a third recording parameter in the linear velocity by a linear interpolation based on first and second recording parameters which are corrected by test writing, replacing all the recording parameters for an outer circumference of an optical disk from a radius position where the linear velocity becomes Cx, with the third recording parameter; and (4) restart the recording with the third recording parameter as a recording condition.

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.
