A method is provided for discriminating the type of a multi-layer optical disc. This method can accurately discriminate the type of a multi-layer optical disc loaded in an optical disc player such as a DVD player, based on the detection time interval between successive focus OK signals. The multi-layer optical disc may have diverse types such as a DVD-dual layer type and a hybrid super audio CD type. In accordance with this method, it is possible to achieve normal servo and signal processing operations according to the type of the multi-layer optical disc.
