摘要： Provided is an optical disc device in which adjustment precision of recording laser power is improved without complication of a processing sequence during recording operation. In response to a recording start instruction, OPC is executed using an inner disc drive zone to set an initial value of recording laser power Pws. Then, when a recording instruction REC(1) is issued, recording is successively performed from the head of a data area using the laser power Pws. After that, when an intermittent standby period T is set, sample data is recorded at the number of times corresponding to the intermittent standby period T in a next recording position, and R-OPC is executed. Therefore, the recording laser power Pws is set again. Then, when a second recording instruction REC(2) is issued, recording is successively performed from a next recording position, that is, a position next to an end portion of data recorded by the first recording instruction REC(1) using the reset laser power Pws. At this time, data corresponding to a head portion of the second recording instruction REC(2) is overwritten on sample data in the head of the recording position.

摘要： The present invention aims to smoothly and adequately adjust recording laser power while an increase in processing load during recording is suppressed. When a recording operation start request is received, OPC is executed with reference to a target β value (βt) of a disc to set recording laser power Pws. Recording operation is performed based on the set recording laser power Pws. When a system is brought into an intermittent standby state, R-OPC is executed, so the recording laser power Pws is adjusted and set again. Then, its subsequent recording operation is performed based on the recording laser power Pws which is set again. When a duration of the recording operation exceeds a maximal waiting time Ts, the recording operation is suspended so that the system is set to a recording standby state. Then, the R-OPC is executed, so that the recording laser power Pws is adjusted and set again.

摘要： A mark level (peak value) is obtained from an RF signal during recording and the mark level (peak value) is divided by a linear value proportional to a recording power to obtain a normalized peak value. The obtained normalized peak value is compared with a target value to adjust a set value of the recording power. The normalized peak value, which is obtained by dividing measurements of the mark level (peak level) by the linear value for normalization, monotonously decreases along with an increase in the laser power. Therefore, the shift direction of the recording power can be detected based on the normalized peak value. Further, a shift of the recording power can be appropriately detected based on the normalized peak value level because a change in the normalized peak value level in a power margin range is relatively large.
摘要翻译：在记录期间从RF信号获得标记电平（峰值），并且将标记电平（峰值）除以与记录功率成比例的线性值以获得归一化峰值。将获得的归一化峰值与目标值进行比较，以调整记录功率的设定值。通过将标记电平（峰值电平）的测量除以用于归一化的线性值获得的归一化峰值随着激光功率的增加而单调减小。因此，可以基于标准化的峰值来检测记录功率的移动方向。此外，由于功率余量范围内的归一化峰值电平的变化相对较大，所以可以基于归一化峰值电平适当地检测记录功率的偏移。

摘要： An object of the present invention is to further increase the speed of tilt control while suppressing a useless tilt control operation. Values of focus bias voltages (reference bias values V1 to V6) at a plurality of radial positions P1 to P6 are obtained and stored using a reference disk with a high flatness precision. Prior to a recording and reproducing operation, the values of focus bias voltages (Fo bias values vs1 to vs6) at the radial positions P1 to P6 are obtained, and each of tilt amounts T1 to T6 at the respective radial positions is obtained from a differential value between the reference bias value and the Fo bias value at each radial position. During recording/reproduction, a radial position Pn placed immediately before the recording/reproducing position is detected. Then, tilt control is performed with a tilt amount Tn at the radial position Pn being set as the tilt amount at the recording/reproducing position.

摘要： A meandering groove is formed in a digital disk (10) with a wobble signal that is wobbled to reproduce a clock signal. The wobble signal is read out by an optical head (26). An address detection circuit (40) detects an address signal that is multiplexed with the wobble signal. A PLL oscillation circuit (24) provides a clock signal in synchronization with the wobble signal. Data is modulated by a modulation circuit (16) according to the clock signal and a timing signal based on the address signal, and recorded on the digital disk (10). In reproduction, a RF signal in the wobble signal is converted into a digital signal by an A/D converter (42). The signal is demodulated by a demodulation circuit (44) for data output.
