<p>Provided are an optical information storage medium in which information on recording layers that have the same reproduction channel characteristics or different reproduction channel characteristics, and a recording/reproducing method for the optical information storage medium. Nominal recording speed information is recorded in a read-only zone, and maximum and/or minimum recordable speed information is recorded in a recordable zone of the area other than a user data area. The optical information storage medium addresses the case where the nominal recording speed is not satisfied due to errors occurring during the manufacture of the storage medium. Thus, the defective disc proportion can be reduced, and loss of user data due to application of inaccurate recording layer information can be prevented.</p> |
