Abstract

A radiation recording structure for use in an information storage device having focused write and read radiation beams includes a substrate supported reflective layer, an active structure supported on the reflective layer. The structure also includes a dust defocusing layer as an outer surface for the structure for defocusing the image of dust on the outer surface and an aluminum adhesion layer between the dust defocusing layer and the active recording layer. The adhesion layer is transparent to the radiation beams and provides surface energy to draw the defocusing layer and the recording layer together.
