MASTER RECORDING APPARATUS, MASTER RECORDING METHOD, MASTER FOR STAMPER CONTAINING HEAT-SENSITIVE RESIST MATERIAL, AND METHOD OF FORMING FILM OF HEAT-SENSITIVE RESIST MATERIAL |
摘要 |
<P>PROBLEM TO BE SOLVED: To provide a master recording apparatus and a master recording method by which a pit having a shape wherein the shapes of the top of a recording mark and the end of the recording mark are symmetrical can be formed with high reproducibility. <P>SOLUTION: The pit having a shape wherein the shapes of the top of the recording mark (recording start position) and the end of the recording mark (recording end position) are symmetrical can be formed on a stamper master with high reproducibility. As a result, the noise level/jitter degree of a reproduction signal obtained by reproduction from an optical disc as a final product can be reduced, thereby manufacturing at low cost the optical disc from which a signal can be stably reproduced. <P>COPYRIGHT: (C)2010,JPO&INPIT |
