US 2005/0237888 A1 · Anti-burn method

Abstract

The present invention provides an anti-burn method for a recording and reproducing apparatus when mechanism problem happen. The method includes: low-pass filtering a center error (CE) signal which shows the position of an optical pickup unit; detecting if the filtering CE signal is lower than a threshold value, then stopping recording and marking a stop point when the filtering CE signal is lower than the threshold value. The method further includes: continuing recording process from the stop point when the filtering CE signal is higher than the threshold value. The continuing recording process includes: preparing recording data; seeking the stop point of a disk; and continuing recording the disk from the stop point.
