发明名称 OPTICAL RECORDING MEDIUM
摘要 <P>PROBLEM TO BE SOLVED: To provide an optical recording medium in which high-density recording is made possible, further, reproduction durability is improved and cross erase is reduced. <P>SOLUTION: In an optical recording medium 1 wherein a recording layer 4, a second absorbing layer A2 and a heat radiating layer 6 are formed in order from the incidental side of laser light L, the second absorbing layer A2 is configured such that its attenuation coefficient (k) satisfies a condition of 0.06&le;k&le;1.0 in a wavelength of the laser light L. In such a case, preferably, a first absorbing layer A1 is formed on the incidental lateral side of the laser light L in the recording layer 4 such that the attenuation coefficient (k) of the first absorbing layer A1 satisfies the condition of 0.06&le;k&le;1.0 in the wavelength of the laser light L. <P>COPYRIGHT: (C)2004,JPO
