发明名称 OPTICAL RECORDING MEDIUM
摘要 <P>PROBLEM TO BE SOLVED: To provide an optical recording medium capable of recording data in a high density with the excellent C/N (carrier to noise ratio) of a reproduced signal. <P>SOLUTION: This optical recording medium is for recording and/or reproducing signals by irradiating a recording layer with light. In addition, in this recording medium, a first region 20a showing a high light absorption factor and a second region 20b which almost does not absorb the light constitute a pattern of separated phases on the light incident side surface of at least the recording layer. <P>COPYRIGHT: (C)2005,JPO&NCIPI
