发明名称 Information reproducing / recording apparatus
摘要 <p>The present invention provides an information reproducing/recording apparatus capable of executing tracking servo normally in short time at the time of loading an information recording medium. At the time of executing a tracking servo process on a BD (Blu-ray Disc)-R capable of recording information selectively on a land track or a groove track during loading of the BD-R, the polarity of a tracking error signal adapted to trace of the land or the groove is temporarily determined on the basis of statistical information indicating which one of the BD-R that records information on the land track and the BD-R that records information on the groove track is more frequently used. On the basis of the tracking error signal of the polarity, an optical pickup is driven to execute tracking servo.</p>
