HOLOGRAPHIC DISC WITH IMPROVED FEATURES AND METHOD FOR THE SAME

摘要

PURPOSE: A holographic data storing disc and a method for providing an improved holographic data storing disc are provided to supply different multimedia content on one holographic disc. CONSTITUTION: At least one among multimedia content(11) is locked through at least one encoding key. A disc(10) rotates a central shaft(26) and an optical reader(28). The optical reader emits reading beam and reflecting beam. A processor(36) processes data from reflected beam to output data stream(42).
