Abstract:
1. A method for determining disc type in an optical disc device capable of recording and/or reproducing data on various types of discs, the method comprising: (a) storing cumulatively disc types of previously inserted optical discs; (b) generating a cumulative frequency distribution of the stored disc types; (c) selecting, among all of the disc types of the previously inserted optical discs, a disc type corresponding to the most frequent disc type in the cumulative frequency distribution; (d) performing an initialization procedure corresponding to a preset disc type for a disc loaded in the optical disc device, wherein the initialization procedure corresponding to the preset disc type is an initialization procedure corresponding to the selected disc type; and (e) performing a disc type determination procedure to determine a disc type of the loaded disc if the initialization procedure fails, wherein the steps (a) - (e) are performed each time a disc is loaded in the optical disc device.
