摘要： A write power adjustment method makes it possible to set optimum write power with high precision. Trial writing is conducted by using write power Pw,m (where m is an integer) of a plurality of kinds, and a modulation M,m associated with each write power is calculated. Optimum asymptotic power Pasy-opt is calculated by performing predetermined computation by using reference asymptotic power Pasy-ref and reference write start power Pws-ref which are previously determined for each medium. An evaluated value S,m=M,m×(Pw,m−Pasy-opt) is calculated by using the optimum asymptotic power Pasy-opt. Write power Pw that makes the evaluated value S equal to zero when applying straight line approximation to a relation between the write power Pw,m and the evaluated value S,m is calculated as optimum write start power Pws-opt. And optimum write power Pw-opt is found by performing predetermined computation on the optimum write start power Pws-opt.

A driver having a function of controlling rise/fall times and an overshoot amount of an optical waveform is used to optimize an optical waveform that changes in recording under the influence of a component of a laser and the like.

摘要： A write power adjustment method and optical read/write apparatus for accurate optimum write power setup. Different levels of write power Pwm are used to perform a test write and calculate a modulation Mm corresponding to each level of write power Pwm. Different write power compensated values Pcn are used to calculate an evaluated value Smn=Mm×(Pwm−Pcn). Pcn that maximizes the linearity of the relationship between compensated write power (Pwm−Pcn) and evaluated value Smn is determined as an optimum write power compensated value PcO. Compensated write power PthO that provides a modulation of zero, that is, an evaluated value SmO of zero, when the relationship between compensated write power (Pwm−PcO) for PcO and evaluated value SmO is subjected to linear approximation is determined. PthO and optimum write power compensated value PcO are used to calculate a write power threshold Pth=PthO+PcO. A predetermined calculation is performed on Pth to determine optimum write power Popt. In contrast to a conventional write power adjustment method (κ method), the present invention makes it possible to accurately adjust for the optimum write power even when the optical disc's write power Pwm-to-evaluated value M×Pw relationship is not linear or its modulation M varies.
摘要翻译：一种写入功率调整方法和光学读/写装置，用于精确的最佳写入功率设置。使用不同级别的写入功率Pwm进行测试写入，并计算与写入功率Pwm对应的调制Mm。不同的写功率补偿值Pcn用于计算评估值Smn = Mmx（Pwm-Pcn）。将补偿写入功率（Pwm-Pcn）与评估值Smn之间的关系的线性度最大化的Pcn被确定为最佳写入功率补偿值PcO。确定当PcO的补偿写入功率（Pwm-PcO）与评估值SmO之间的关系经受线性近似时，提供零调制的补偿写入功率PthO，即评估值SmO为零。 PthO和最佳写功率补偿值PcO用于计算写功率阈值Pth = PthO + PcO。在Pth上执行预定的计算以确定最佳写入功率Popt。与传统的写入功率调整方法（kappa方法）相比，本发明即使当光盘的写入功率Pwm至估计值MxPw关系不是线性或其调制M时也可以精确地调节最佳写入功率不一样
