PROBLEM TO BE SOLVED: To provide a data readout system having a non-uniform ADC resolution and a related method therefor. SOLUTION: A data readout system with nonuniform resolution has a pick up head for reading data stored in an optical disk and generating an analog signal; a reference voltage unit for producing a plurality of reference voltage levels, so that the voltage differences between two adjacent reference voltage levels are not all the same; a plurality of comparators for comparing the reference voltage levels with the analog input signal and generating comparison results; and an encoder for encoding the comparison results into a digital signal.
