Holographic Recording

摘要

Optical disks, such as Blu-Ray, are popular removable recording media. However, an optical disk for the Super Hi-Vision (SHV) system will require 100 times the recording capacity and data-transfer-rate of today's Blu-Ray disks. We are working on a holographicrnrecording technology that is capable of three-dimensional volume recording as a way of storing SHV programs conveniently.rnHolographic recording and reproduction employs data page in which black and white bits in the medium correspond to the "0" and "1" values of a digital signal (Figure 1).
