发明名称 OPTICAL DISK APPARATUS AND INFORMATION RECORDING APPARATUS
摘要 <P>PROBLEM TO BE SOLVED: To provide an optical disk apparatus and an information recording apparatus capable of reducing an error rate during reproduction of a recorded signal, and improving reliablity of an entire data recording/reproducing system. <P>SOLUTION: Instead of generating a recording-system clock signal from a wobble signal that is susceptible to noise, a necessary recording-system clock frequency is calculated from address information that has been modulated and recorded therein, and a signal of this frequency is generated from a stable reference signal source, such as a quartz oscillator, by a synthesizer method and used as a recording-system clock. <P>COPYRIGHT: (C)2008,JPO&INPIT
