FIELD: information technology.
SUBSTANCE: information storage medium contains the first information storage layer containing the first optimal power control domain and the second information storage layer neighbouring with the first information storage layer and containing the second optimal power control domain. The first and the second optimal power control domains do not overlap, buffer areas are on one side of the first optimal power control domain and on one side of the second optimal power control domain.
EFFECT: 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.
