ABSTRACT:
An optical data storage system is contemplated, one employing a data-modulated writing laser beam (FIG. 2: .circle.L ) with improved associated optical media (FIG. 2), these characterized by multiple layers (FIG. 2:c,d,e,f,g)--more particularly, a highly reflective aluminum layer (c), a relatively transparent polymer spacer layer (d) overlying the reflective layer, and an optical absorber (recording) layer (e) overlying the spacer layer, plus an overcoating structure, e.g., as a "soft pad" layer (f; e.g., a fluoropolymer) on the absorber, with a "Hard" layer (g; e.g., a radiation-cured acrylic) laid over the "soft pad" as an outer protective overcoat. "Spiral" coating techniques (FIG. 3) are specified for applying the "Hard" layer.
