METHOD FOR IMPROVING THE PLAYABLITIY OF OPTICAL INFORMATION STORING MEDIA WHICH HAS ANY DEFECT REPRODUCING APPARATUS

摘要

A method for improving reproducibility of an optical information storage media reproducing apparatus is provided to reduce/delay a servo hold time and to apply track and focus offsets when the defect process fails, thereby increasing the defect handling performance. A method for improving reproducibility of an optical information storage media reproducing apparatus comprises the steps of: uploading an optical disk(S10); generating focus and tracking servo error signals to adjust the servo automatically(S20); holding the same servo as the track error servo during a defect detecting time(S40); reading data of the optical disk while holding the servo(S50); applying track and focus offsets to a servo value before detecting the defect(S70); delaying the servo hold(S80); reading the data with the track and focus offsets reflected(S90); recovering the track and focus offsets into a normal value(S100); and, if the data is not normally read out, re-reading the data while alternating between a hold-off state and a hold-on state(S110,S120).
