  • Optical recording using an agglomerating recording medium which changes reflectivity upon recording
    Patent number: 5177732
    Abstract: Recording methods, systems and media for recording and read-out with relatively low-power laser means to write digital data "bits" (as reflectance changes) for high density computer storage. One preferred medium comprises a disk support having an "anti-reflective" surface on which is laid a non-continuous "information layer" adapted to absorb recording radiation (from laser beam), and so "write" the bits, by "agglomerating" (coalescing).The information layer exhibits suprisingly high sensitivity, apt for low power recording, and extended archival stability; more suprising, it appears to be formed without any evidence of the usual ablation, "pit formation" or other deformation.

  • Method of coating an optical media
    Patent number: 5171606
    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.
