INFORMATION RECORDING MEDIUM AND METHOD FOR FABRICATING SAME |
摘要 |
<p>To obtain high durability even when a recording material which causes big cubical expansion is used for a recording film of an information recording medium. An information recording medium 10 comprises a substrate, a recording film provided on the substrate, and a dielectric film provided on the substrate. The recording film is made of recording material configured to cause cubical expansion by light energy irradiation. The dielectric film is made of ZrO 2 and Cr 2 O 3 . This prevents the generation of cracks in the dielectric film 4 and the immersion of moisture to the recording film 6 even when the recording material causes cubical expansion due to light energy irradiation.</p> |
