哈他瑜伽培训摘要:A recording technique for performing data recording onto a hologram recording medium in accordance with information on phas by performing spatial light pha modulation as spatial light modulation corresponding to recording data, and a reproducing technique for reproducing recorded data by properly reading information on phas recorded as described above are suggested. A signal beam having a pha modulation pattern provided thereto corresponding to recording data and a reference beam having a specific pha modulation pattern provided thereto are applied to the hologram recording medium. Thus, recording data can be recorded onto the hologram recording me
dium in accordance with information on phas. In addition, at the time of reproduction, a reference beam and a DC beam having the entire pha who pha difference with respect to a reference pha within the reference beam is π/2 are applied to the hologram recording medium. By providing a pha difference bad on π/2 as described above, the pha of a reproduction beam obtained from the hologram
recording medium in accordance with application of the reference beam and the pha of the DC beam can be t to be the same. Thus, the DC beam can be added as a component of an amplitude of "1" to the reproduction beam. By reading the reproduction beam to which the DC beam is added as described above, recorded information on phas can be correctly read, and recorded data can be reproduced in accordance with the pha information.
