ABSTRACT:
A method for determining disc type in an optical disc device is provided. The device performs a disc initialization procedure for a disc loaded into the device, assuming that the loaded disc type is a preset disc type, and checks whether or not the initialization procedure fails. If the initialization procedure fails, the device performs a series of disc type determination operations to determine the loaded disc type. The device cumulatively stores the initialized disc type or the determined disc type, and updates the preset disc type using cumulative frequency distribution of the stored disc types. The user may also select the loaded disc type by manipulating a switch provided on the optical disc device. The device can quickly determine the loaded disc type, reducing the time the user must wait until a desired operation is performed.
