<P>PROBLEM TO BE SOLVED: To provide an optical recording medium featuring the capability to prevent a recording material from developing a deflection power with data unrecorded and develop the deflection power after recording, with a significant quantity of signal fluctuation and also, deal with rapid data writing, and further, to provide a recording material applicable to DRAW (direct read after write) type disc systems of a next generation and thereafter. <P>SOLUTION: This optical recording medium is characterized in that: at least, one of the constituent materials of a recording layer of the photorecording medium capable of recording and/or regenerating data, is a polymer material, and further, that the main chain of the polymer material is a block copolymer with a repeating unit of A-b-[B-C], and either one of the [B-C] parts of the polymer main chain has a light absorber grafted which can assume an order or a disorder state. <P>COPYRIGHT: (C)2009,JPO&INPIT |
