ABSTRACT:
Recording media for recording information "bits" in response to activation of a laser beam, the media including a recording layer adjacent a "soft pad" layer above and/or below (e.g., a vacuum-evaporated reconstituted fluoropolymer), especially as a "soft pad overcoat". A "hard cap" is overlaid on such a "soft pad" overcoat (e.g., a radiation-cured acrylic) as an outer protective sealing coat. The soft pad may be rendered under the recording layer as a spacer layer.
