    Abstract: A method of reproducing data from an optical storage medium includes reproducing write protection information from the optical storage medium. The optical information storage medium includes a lead-in area, a user data zone in which user data is recorded, and a lead-out area. The write protection information is recorded in at least one of the lead-in area and the lead-out area, together with defect management information. The data is recorded and/or reproduced according to the defect management information and the write protection information. The write protection information indicates a size of a write protected area differentiated from a plurality of sizes of write protected areas of the optical information storage medium.

    Abstract: An information storage medium and an apparatus for recording and/or reproducing the information storage medium are provided to control optimal recording power without an influence of an optimal power control (OPC) area in a layer upon an OPC area in a different layer. The information storage medium includes at least one information storage layer including an optimal power control area for obtaining an optical recording condition. OPC areas in adjacent information storage layers are disposed within different radiuses of the information storage medium. Accordingly, even when the information storage medium is made eccentric or has a manufacturing error, a recording property of the information storage medium is prevented from being degraded due to an influence of an OPC area in an information storage layer upon an OPC area in an adjacent information storage layer.
