Abstract:
A method for identifying a type of an optical disk includes the steps of: turning on a laser diode of an optical pickup and focusing light emitted from the laser diode on the optical disk; moving the optical pickup to obtain a plurality of servo signals; reading a specific servo signal from the servo signals; and determining the type of the optical disk according to the count of enabled times of the specific servo signal and a corresponding enabled time period.
