ABSTRACT:
For an optical data storage system employing a data-modulated writing laser beam, optical media are described which include a highly reflective aluminum layer, a relatively transparent polymer spacer layer overlying the reflective layer and an optical absorber (recording) layer overlying the spacer layer,--plus an overcoat structure including a "soft pad" layer (e.g., fluoropolymer) on and/or under the absorber plus a "hard" overcoat layer (e.g., radiation-cured acrylic) laid over the "soft pad" as an outer protective overcoat.
