Paper Abstract

A write-once optical data storage media has been developed which is suitable for tape formats. The recording layer is a metal alloy system which is sputter deposited onto polymeric substrates as a single-layer thin film. The media are manufactured using a continuous sheet process, where the reflectivity of the film at 840nm can be selectively varied between 30 and 70%. These films have been characterized for laser write sensitivity, optical properties, surface chemistry, and environmental stability. An abrasion resistant hard overcoat is applied directly onto the active surface in a second vacuum deposition step. The media performance has been found to be compatible with direct hard-overcoats with no degradation in write sensitivity.
