FIELD: physics, computer facilities.
SUBSTANCE: non-rewritable optical BD-WO-type disk is proposed along with the method and device designed to control aforesaid optical data carrier. Proposed data carrier comprises a temporary area of defects control and final area of defects control. Proposed method comprises recording temporary data of defects control into aforesaid temporary area of data carrier defects control. Note here that defects control temporary data incorporates the disk usage control data indicating data carrier write-on state.
EFFECT: high-efficiency optical data carrier.
