Claim:
An optical disk player discriminating a type of an optical disk loaded in the optical disk player, wherein the optical disk has a Burst Cutting Area (BCA) which stores a BCA code including a disk code, the BCA code having at least one of a corresponding error detecting code and an error correcting code, indicating the type of disk, the optical disk player comprising: an optical pickup to retrieve the BCA code from the optical disk; a digital signal processor (DSP) to demodulate the BCA code; and a processing unit to extract the disk code and detect an error in the disk code using the error detecting code or correcting an error in the disk code using the error correcting code from the demodulated BCA code, to retrieve information having disk codes corresponding to a plurality of different types of optical disks previously stored in the optical disk player, and to determine the type of the optical disk loaded in the optical disk player by comparing the extracted disk code with the information.
