  • Storage medium
    Patent number: 7892721
    Abstract: The invention relates to a storage medium for storing information/data, wherein the storage medium comprises a dielectric storage material, more particularly a disk-shaped storage material on which a metal ion donor medium is arranged or can be applied on at least one side thereof. Metal ions can be transferred from the donor medium into the storage medium by exposing the storage medium to radiation, more particularly to laser radiation. The invention also relates to a storage medium for storing information/data, wherein the storage medium comprises a dielectric storage material, more particularly a disk-shaped storage material having at least one local metal ion doping, wherein the metal ions can be converted into metal particles and/or metal particles agglomerations by means of radiation, more particularly laser radiation.

  • Storage medium
    Publication number: 20060114801
    Abstract: The invention relates to a storage medium for storing information/data, wherein the storage medium comprises a dielectric storage material, more particularly a disk-shaped storage material on which a metal ion donor medium is arranged or can be applied on at least one side thereof. Metal ions can be transferred from the donor medium onto the storage medium by exposing the storage medium to radiation, more particularly to laser radiation. The invention also relates to a storage medium for storing information/data, wherein the storage medium comprises a dielectric storage material, more particularly a disk-shaped storage material having at least one local metal ion doping, wherein the metal ions can be converted into metal particles and/or metal particles agglomerations by means of radiation, more particularly laser radiation.
