    摘要: A read channel apparatus is disclosed for reading data recorded on an optical storage system. An exemplary sampling device samples an analog read signal generating from the optical storage system to generate a sequence of sample values. A subtractor subtracts an estimated DC offset from the sample values to generate a sequence of DC-removed sample values. An equalizer equalizes DC-removed sample values in accordance with a target spectrum to generate a sequence of equalized sample values. First and second interpolators interpolate the equalized sample values to respectively generate sequences of even-time sample values and odd-time sample values. A data sequence composed of the even-time and the odd-time sample values is substantially synchronized to the baud rate. A timing recovery controller controls the interpolators to synchronize the even-time and odd-time sample values to the baud rate.
