<P>PROBLEM TO BE SOLVED: To increase manufacturing efficiency and thereby reduce cost of a multi-layered optical disk recording medium. <P>SOLUTION: A film laminate (multi-layered recordable structure) is manufactured by winding multiple times and punching a film at a rewind core portion. By manufacturing the multi-layered recordable structure by winding and punching, n units of the multi-layered recordable structure may be manufactured at a time corresponding to the number n of surfaces (punching surfaces) disposed at the rewind core portion. Therefore, manufacturing efficiency for the multi-layered optical disk recording medium may increase compared to conventional manufacturing methods. <P>COPYRIGHT: (C)2013,JPO&INPIT |
