Multilayer optical medium for near-field optical recording and reading

摘要

An electro-optical storage system based on an optical head and a multilayer storage medium in a near-field configuration. The heat generated by absorption of a read/write beam adversely affects the interfacing between the optical head and the medium. The medium has a thermal insulation dielectric layer and/or a heat-dissipating layer to reduce thermal feedback from the medium to the optical head.
