Abstract
An improved demodulator principally for receiving dibits from a servo track and generating a position error signal responsive to the servo head position relative to the track as indicated by the dibit signal. The invention improves the functioning of the demodulator for movement of the servo head at both high and low speeds and when noise is encountered in the dibit signal.
