Abstract (en)
[origin: EP1475786A1] It is an object of the present invention to provide an information recording method for recording information in a data rewritable type optical recording medium having a plurality of information recording layers whereby a sufficiently high erasing efficiency can be ensured when data recorded in any one of the information recording layers are directly overwritten. In the information recording method according to the present invention, information is recorded in an optical recording medium 10 having at least a stacked L0 layer 20 and L1 layer 30 by projecting a laser beam thereonto via a light incidence plane 13a. In the case where information is to be recorded in the optical recording medium 10, information is recorded in the L0 layer 20 using an off-pulse recording format and information is recorded in the L1 layer 30 using an on-pulse recording format. As a result, even in the case of directly overwriting data recorded in either of the L0 layer 20 or the L1 layer 30, a sufficiently high erasing efficiency can be ensured. <IMAGE>
