METHOD OF RECORDING DATA IN AN OPTICAL DATA STORAGE MEDIUM AND AN OPTICAL DATA STORAGE MEDIUM

摘要

PURPOSE: A method for recording data in an optical data storage medium and an optical data storage medium are provided to record data in a hologram data medium without having an effect on other layer of data during a recording process. CONSTITUTION: An optical data storage medium including reactant is provided. An interference pattern is irradiated to a volume element of the optical data storage medium. Generated acid is reacted with at least one protected chromophore. The refractive index change is generated in the volume element by forming chromophore. An optically legible data is generated by generating the refractive index change corresponding to the interference pattern in the volume element.
