Filed: 2008-09-30
Abstract: <P>PROBLEM TO BE SOLVED: To provide a focal position adjustment method for easily performing defocus adjustment and thereby accurately reading/writing information, and to provide an optical disk device.  <P>SOLUTION: In order to accurately read information from a track, a focus position F<SB>RD</SB>for reading is set to a focus position F<SB>RF</SB>where an amplitude of a RF signal is sufficiently large. In order to accurately write information in a track, however, it is preferable that a focus position F of an optical beam is set to a focus position where an amplitude of a TE signal is equal to or more than a sufficiently large TE reference value A<SB>TE</SB>, so that the focus position F is increased based on the focus position F<SB>RF</SB>. In this case, while the amplitude of the RF signal decreases as indicated by an arrow in the figure, the amplitude A of the TE signal increases as indicated by a white arrow in the figure to become equal to or more than the TE reference value A<SB>TE</SB>. The focus position F at this time is used as a focus position T<SB>WR</SB>for writing.  <P>COPYRIGHT: (C)2010,JPO&INPIT
