Abstract

Accelerated ageing tests on discs with Te-alloy films for ablative digital optical recording show that these media meet the requirements for their applications in long-term data storage. In these tests, discs of the air-sandwich type with non-sealed (open) as well as sealed cavities were subjected to cyclic high temperatures (25-65°C) and high humidity (95% RH) conditions. "Open" discs incorporating pure Te as ablative material cannot with-stand such severe conditions for more than a few days whereas "open" discs applying Te-Se based alloys with 60 to 80% Te content have not reached end of life after 100 days storage under the same conditions. After such a period of accelerated ageing, hermetically sealed discs do not show any significant ageing effects at all. Ageing is defined in terms which are relevant to optical recording, such as sensitivity for writing, signal to noise ratio of written data and bit error rates and bit error distribution.
