US 2003/0165101 A1 · Optical information recording medium

Abstract

The present invention provides an optical information recording medium capable of recording in the best state regardless of types of optical disks. Since recording strategy of the optical disk differs according to materials and manufacturing methods, the optimal recording strategy is recorded on the optical disk by prerecording. Namely, a format representing as to how the recording strategy of the optical disk is recorded is added to a control data zone, particularly a physical format information area so as to be prerecorded before the shipment of the optical disk on an area used to prevent illegal copying. As a result, the optimal recording strategy for the optical disk can be recorded and heat accumulation on the optical disk is absorbed so that a satisfactory recording/reproduction RF signal can be obtained.
