<P>PROBLEM TO BE SOLVED: To provide a molding die and a stamper for molding which can be homogeneously peeled, even if fluctuation in a ring slit width for blowing out a compressed air in a molding die on releasing of a molded matter from the mold for transferring a micropattern occurrs, an optical disk substrate and an optical information recording medium made by using the above. <P>SOLUTION: The molding die for the optical disk substrate includes two domains of a read only ROM domain and a recording and regeneration domain capable of at least one of recoding, regeneration and erasing on the same plane, has a molding stamper where information related with the ROM domain described above is recorded in a given domain on the inner periphery, and keeps a cavity constructing plane of the mold member where the stamper for molding described above is put on equipped with a means for a temporary pressure accumulating function for compressed air for mold releasing. <P>COPYRIGHT: (C)2007,JPO&INPIT |
