  • Reproduction-only optical disc and method of recording and/or reproducing data on and/or from the same
    Patent number: 7372801
    Abstract: A reproduction-only optical disc has a lead-in area, a user data area, and a lead-out area. Disc related information recorded on at least one of the lead-in area and the lead-out area is recorded by high frequency groove wobbles, and data of the user data area is recorded by pits. Since the high-density reproduction-only optical disc uses the same channels for reproduction signals as a high-density recordable optical disc, the two types of discs are consistent with each other and are compatible with the same disc drives.
