Abstract
A method of identifying ADIP information through counting identical bits and different bits includes generating a wobble clock according to a wobble signal, generating a calculation result according to the wobble signal and the wobble clock, sampling the calculation result to generate a sampling signal and comparing each bit of the sampling signal with each bit of a bit stream containing an ADIP data, counting different bits corresponding to a predetermined logic value for generating a first bit count, and counting identical bits for generating a second bit count, and determining whether the calculation result corresponds to the ADIP data according to the first bit count and the second bit count.
