Zusammenfassung:A method of accessing an optical disc is disclosed. The method includes: enabling a focus servo control without enabling a tracking servo control, and then moving an optical pick-up unit in a radial direction of the optical disc; obtaining at least a first reference signal and a second reference signal according to a laser beam reflected from the optical disc when the optical pick-up unit is moving in the radial direction; and monitoring at least the first reference signal and the second reference signal to identify a boundary of a predetermined data area on the optical disc.
