    • Provided are an optical disc discrimination method, an optical disc device and an integrated circuit that enable to accurately discriminate the type of an optical disc. The optical disc discrimination method comprises a first seeking step (S3) of performing a seek operation to a predetermined reference address in a user data area; a second seeking step (S5) of performing a seek operation from the reference address sought in the first seeking step (S3) to a predetermined target address in a physical information area, an address reading step (S7) of reading a current address at a position sought in the second seeking step (S5), and an optical disc type determination step (S8 through S10) of determining the type of the optical disc loaded in the optical disc device, based on the current address read in the address reading step (S7).
