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.
