摘要： The invention provides an apparatus for demodulating an Address In Pre-groove (ADIP) symbol. The ADIP symbol is carried by a wobble signal of an optical disk and comprises a series of ADIP bits permuted according to one of a plurality of permutation patterns to make up the ADIP symbol. A wobble extraction module extracts the wobble signal from the optical disk. A reference wobble generator generates a reference wobble with the same frequency and phase as a fundamental frequency and phase of a positive wobble cycle of the wobble signal. A waveform difference measurement module then measures a difference between the wobble signal and the reference wobble to obtain a series of difference measurement values respectively corresponding to the ADIP bits. A pattern matching module then compares probabilities of the permutation of the ADIP bits agreeing with each of the permutation patterns according to the difference measurement values to determine the ADIP symbol.

摘要： The invention provides a wobble detection circuit. An exemplary embodiment of the wobble detection circuit comprises an automatic gain control module, an analog to digital converter, a digital band pass filter, and a digital band pass filter. The automatic gain control module amplifies a first input signal and a second input signal detected by a pickup head to the same magnitude to obtain a first amplified signal and a second amplified signal. The adder then subtracts the second amplified signal from the first amplified signal to obtain an analog wobble signal. The analog to digital converter then converts the analog wobble signal to a first digital wobble signal. Finally, the digital band pass filter accepts frequency components of the first digital wobble signal within a pass band and rejects frequency components of the first digital wobble signal outside the pass band to obtain a second digital wobble signal.
