ABSTRACT:
A tracking servo system with a tracking skate detection algorithm is presented. The tracking skate detection algorithm receives a tracking error signal and, takes the absolute value of the tracking error signal and filters the absolute value with a low pass filter. If the filtered signal exceeds a threshold value for a number of cycles exceeding a maximum number, then a tracking skate condition is indicated.
