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： An optimum power set value Pwp1 for Layer 1 obtained by an OPC is used as an initial value Pw21 of the OPC for Layer 2. At this time, an inclination Ia is obtained from an approximation line of a β value for Layer 1 (recording power to the β value) obtained by the OPC. From the β value obtained by performing a test recording at the initial value Pw21 and the inclination Ia, an approximation line of a β value for Layer 2 (recording power to the β value) is obtained. Then, on the obtained approximation line, a laser power for providing a target β value (βt) is obtained, and set as an optimum power Pwp2 for Layer 2. Thus, an optimum power setting conforming to characteristics of a disc can be performed. As a result, setting the optimum power for Layer 2 can be performed more smoothly and quickly.

摘要： In order to set optimum laser power for a disk smoothly and appropriately with a small number of times of test writing, an integrated value Sn is obtained from each kind of laser power Pwn set for the test writing and the modulation factor m(Pwn) of a reflection light intensity obtained through the test writing with the laser power Pwn using an expression “Sn=m(Pwn)×Pwn2”, laser power Pwth is obtained at which the modulation factor m(Pwn) becomes zero when relational characteristics of the integrated value Sn and the laser power Pwn are linearly approximated, and optimum laser power Pw is set based on the laser power Pwth. Here, the optimum laser power Pw is obtained from the target γ value of the disk using an expression “Pw=Pwth×{1+1/(γ+1)}”. The target γ value is obtained from an ADIP of the disk.
