ABSTRACT:
Methods for rendering a recording medium for use with a recording laser beam providing light of a given energy and frequency, where the medium is characterized by a light-reflecting structure with a light-absorbing record layer thereon and a sealing overcoat on the record layer, the light-absorbing record layer being prone to exhibit micro-excursions and/or micro-deformation during laser recording thereon, and a transparent "soft-pad" isolation layer is interposed, between the light-absorbing layer and the overcoat, this soft pad having a thickness and other characteristics such that the absorber layer is constrained little, or not at all, in the course of being written-upon with the laser, the soft, pad thus functioning to isolate the absorber layer thermally and mechanically, as well as to help defocus dust, etc.
