Title: Optical disk device
Inventor: MASHIMO AKIRA
IPC: G11B7/00
Filed: 2002-03-27
Granted: 2006-04-21
Abstract: This invention relates to an optical disk device in which the quantity of jitter may be accurately detected for the adjustment of focus servo etc. According to this invention, the reflected light from an optical disk 10 is converted into RF signal by an optical pickup section 12, amplified by an RF amplifier 14, and then supplied to an equalizer 16. The boost of the equalizer 16 is set to be zero when making an adjustment, while set to be a predetermined finite value (for example, +20 Db) upon normal recording or regenerating time. By setting the boost to be zero, the delay characteristic becomes flat within the range of RE signal between 3T to 11T. We may detect the accurate quantity of jitter from the integrated value of the phase shift of 3T to 11T, and adjust the optical pickup section 12 so as to minimize the quantity of jitter.
