Abstract:
In a multilayer optical disc having information layers conforming to a plurality of different optical disc standards, because the type of each information layer is not recorded in the other information layers, in read and write operations by a compatible optical disc device conforming to a plurality of optical disc standards, every time the information layer being accessed changes, it has been necessary to read the type of the information layer and select a method of generating a tracking error signal adapted to the type of information layer, so access has taken time. In order to solve the above problem, in the optical multilayer disc according to the present invention, having information layers conforming to a plurality of different optical disc standards, in an area in one of the information layers, information about the other information layers is recorded. The time required to access the other information layers can be reduced by using this information to select a tracking error signal generating method.

Claim (Index 3):
A reproducing method for reproducing an optical disc, containing a first recording layer, having a track upon which a first laser beam is focused, and providing a management area on said first recording layer, said management area having first recorded information representing if a second recording layer upon which a second laser beam is focused is present in said optical disc and second recorded information representing if a third recording layer upon which a third laser beam is focused is present in said optical disc, said reproducing method comprising:\n reading said first recorded information and said second recorded information on said management area; and reproducing data recorded on said first recording layer, wherein a wavelength of said second laser beam is longer than that of said first laser beam, wherein a wavelength of said third laser beam is longer than that of said second laser beam, wherein said first recorded information and said second recorded information comprise two bits respectively, wherein said first recorded information indicating said second recording layer represents absence of said second recording layer by bit values of 00, wherein said second recorded information indicating said third recording layer represents absence of said third recording layer by bit values of 00.
