Optical recording medium and method

摘要

A recordable/replayable optical recording medium includes a substrate 10, a thin metal film 20 formed on the substrate 10, a reflective layer 40 arranged above the thin metal film 20, a buffering layer 30 interposed between the reflective layer 40 and the thin metal film 20 which is arranged to be deformed by heat from a laser beam, and a protecting layer 50 for protecting the deposited layers. Recording is facilitated by adopting the buffering layer 30 and compatibility with a conventional CD player is possible. Since expensive organic dyes are not necessary, manufacturing costs can be reduced and productivity can be greatly improved.
