Abstract
An apparatus and a method for generating ATIP data is provided. The apparatus generates ATIP data from a wobble signal of a re-writable compact disc. The apparatus includes a frequency demodulator for demodulating the wobble signal to generate an original ATIP data signal; an ATIP clock generating circuit for generating an ATIP clock signal based on the wobble signal; and a data generating circuit, coupled to the frequency demodulator and the ATIP clock generating circuit, for generating the ATIP data based on the number of measurement periods for which the original ATIP data signal is at a first logic level during one period of the ATIP clock signal. This apparatus uses this number and the bi-phase rule to precisely generate ATIP data.
