Abstract
A device for controlling access to an optical disc includes a control word calculator and a numerically controlled oscillator (NCO). The control word calculator is arranged to calculate a control word corresponding to a radius where the optical disc is accessed. In addition, the NCO is arranged to generate an output frequency according to the control word, wherein the output frequency is utilized for accessing the optical disc. An associated method for controlling access to an optical disc includes: calculating a control word corresponding to a radius where the optical disc is accessed; and generating an output frequency according to the control word, wherein the output frequency is utilized for accessing the optical disc.
