<P>PROBLEM TO BE SOLVED: To provide an optical disk device of a CAV system using a write strategy circuit which is hardly influenced by noise and can be controlled by a high resolution. <P>SOLUTION: The optical disk device of the CAV system for recording information by irradiating the surface of an optical disk 3 with a laser beam comprises a PLL circuit 11 for oscillating prescribed clock signals by the multiplication number of a reference clock and the write strategy circuit 9 for adjusting the laser beam outputted corresponding to the oscillated prescribed clock signals from the PLL circuit 11, and the PLL circuit 11 uses a crystal oscillator as the reference clock. <P>COPYRIGHT: (C)2007,JPO&INPIT |
