Semiconductor device, write strategy generating method, and write strategy generating program
摘要：
A semiconductor device mounted in an optical disk apparatus controls writing and reading of data in and from an optical disk. The device performs first processing for adjusting a write strategy in such a manner that based on error information corresponding to a shift in the phase of a reproduction signal with respect to a channel clock signal for data reproduction, which is generated based on the reproduction signal read from the optical disk, the value of the error information related to a plurality of recording marks to be evaluated becomes minimum as a whole. The device also performs second processing for adjusting a write strategy in such a manner that the value of the error information related to a desired recording mark becomes small.

安装在光盘装置中的半导体装置控制从光盘读出数据的数据。 该装置执行用于调整写入策略的第一处理，使得基于与基于再现信号读取生成的数据再现的通道时钟信号相对应的再现信号的相位移相对应的误差信息 从光盘开始，要评估的多个记录标记相关的错误信息的值整体上变得最小。 该装置还执行用于调整写入策略的第二处理，使得与所需记录标记相关的错误信息的值变小。
