Abstract:
A method for generating a feedback signal in optical disc drives is disclosed. Firstly RF signal is generated by a pickup head and coupled to a converter to generate a digital signal. Then a detector generates a plurality of pseudo-jitter according to the digital signal. Thereafter a calculator receives the said pseudo-jitter and calculates for outputting a feedback signal to the pickup head.
