Summary: | PROBLEM TO BE SOLVED: To provide a holographic data storage device in which angles of incidence to a recording medium of a reference beam and a data beam are never changed in among pages. SOLUTION: This device has a spherical holographic recording medium 102 and an addressing means for selectively striking a data beam 110 and a reference beam 108 on prescribed positions by rotating the recording medium 102. Then, picture data included in the data beam are to be recorded on the recording medium 102 and a data page beam 112 is to be reproduced from the recording medium 102. |
