    Abstract: PROBLEM TO BE SOLVED: To perform tracking servo using a recording signal in a grooveless optical disk.SOLUTION: Trial writing is performed on a plurality of recording conditions, a recommended recording condition which can acquire excellent playback signal quality and tracking error signal quality from a trail writing signal is determined, and recording is performed by using the recommended recording condition. A recording condition determined by an OPC executed previously to recording is used to perform recording so as to make a signal adjacent to at least two tracks or more, and when tracking error signal quality obtained from a recording signal coincides with a targeted value of tracking error signal quality of a corresponding medium, the determined recording condition is used to perform recording.

    Abstract: PROBLEM TO BE SOLVED: To improve the work efficiency of master disk strategy adjustment and prevent waste of materials relating to manufacturing of an optical disk while preventing degradation in the quality of the optical disk as a final product.SOLUTION: Progressing once to creation of an optical disk recording medium, a target value of an evaluation value of a master disk is calculated from the difference between the evaluation value of the master disk and an evaluation value of the optical disk recording medium, and then master disk strategy adjustment (strategy adjustment for driving the evaluation value of a master disk recording signal into the above-described target value) is carried out so as to make the evaluation value match the target value. The number of times that the optical disk recording medium required for the strategy adjustment is created can be suppressed to at least one time. Thus, the work efficiency of master disk strategy adjustment can be improved and waste of materials relating to manufacturing of the optical disk can be prevented. At this time, since the strategy adjustment is performed in reflection of the evaluation value of the optical disk recording medium actually created, the signal quality of the optical disk recording medium can be accordingly improved.

    Abstract translation: 要解决的问题：提高主盘策略调整的工作效率，并且防止与制造光盘有关的材料的浪费，同时防止作为最终产品的光盘的质量下降。 解决方案：一次执行光盘记录介质的创建，根据主盘的评估值和光盘记录介质的评估值之间的差来计算主盘的评估值的目标值 ，然后执行主盘策略调整（用于将主盘记录信号的评估值驱动到上述目标值中的策略调整），以使评估值与目标值相匹配。 创建策略调整所需的光盘记录介质的次数可以抑制至少一次。 因此，可以提高主盘策略调整的工作效率，并且可以防止与光盘的制造有关的材料的浪费。 此时，由于通过反映实际创建的光盘记录介质的评估值来执行策略调整，因此可以相应地提高光盘记录介质的信号质量。 版权所有（C）2013，JPO＆INPIT
