ABSTRACT:
An optical memory for optically storing and reproducing data comprises a substrate, an under layer and a recording layer. The under layer contains carbon and fluorine. The recording layer contains carbon and at least one of a metal and semiconductor material. The under layer acts as a barrier to H.sub.2 O and O.sub.2 diffused through the substrate toward the recording layer. The optical memory has an excellent write sensitivity and anti-oxidization characteristics. Also, the optical memory is capable of stable data storage over a long time period.
