ABSTRACT:
A method of identifying a type of a disc includes steps of: obtaining a first address of a first position on the disc; moving a pick-up unit to a second position of the disc; obtaining a second address of the second position; calculating a difference between the first address and the second address; and identifying the type of the disc by comparing the difference with a predetermined value.
