Vibration interpreter for electronic shock prevention of CD machine

THe present invention relates to an electronic vibration-proofing vibration judgement equipment for optical disk drive, and is characterized by that its interior possesses error contour production/comparator, judgement reference value regulator and error rate calculator. Said error contour production/comparator can simultaneously pick and judge one-dimensional and two-dimensional quality signal of decoder of optical disk drive so as to display data error contour form due to vibration, and can dynamically change its judgement reference value, and can form a high-efficiency accurate vibration judgement equipment and retain data fetch efficiency and low error rate.
