Abstract
An optical data storage system is contemplated, employing improved optical disk media, these characterized by multiple layers, including various under layers, an optical absorber layer, and overcoating layers, such as a 'soft pad' layer (e.g., a fluoropolymer) overlaid with a 'Hard' layer (e.g., a radiation-cured acrylic) as an outer protective overcoat. Taught are 'Spiral' coating techniques (FIG. 3) specified for applying the 'Hard' layer and preferably involving: applying the coating mix as arcuate 'bead segments' about the disk center, these being formulated and applied to properly 'set-up' and quickly 'level' (e.g., close enough to one another and 'self-leveling').
