INITIALIZATION METHOD FOR INFORMATION RECORDING MEDIUM

摘要

PURPOSE:To offer initialization method of information recording medium by increasing the sensibility, increasing performance after repeated cylcle and prolonging life in the case of recording and erasing and beeing similiary applicable within low cost. CONSTITUTION:In the initialization method of information recording medium recording information by means of transition between two state of recording materials applying energy of electromagnetic wave, using electromagnetic wave as a energy source of initialization against optical information recording medium and also having a relation of the wave length lambdae and -0.1<=(lambda/lambdae)-1<=0.1 is claimed as a new initialization method of information recording medium.
