HOLOGRAM RECORDING MEDIUM AND ITS MANUFACTURING METHOD |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide a hologram recording medium capable of high density image recording and the accurate reproduction by forming a hologram recording layer considering volume contraction of a composition for a hologram recording medium and without obstruction for recording and reproduction of hologram images. <P>SOLUTION: A method for manufacturing the hologram recording medium includes at least a hologram recording layer formation process for forming a hologram recording layer by hardening while pressurizing and supplying a composition solution for the hologram recording medium in a hologram recording layer formation region on a second substrate. A filling quantity of the composition for the hologram recording medium preferably satisfies the following inequality, <formula 1>: 95V/(100-x)≤V<SB>0</SB>≤110V/(100-x); wherein V denotes volume (cm<SP>3</SP>) of hologram recording layer; V<SB>0</SB>denotes filling quantity (cm<SP>3</SP>) of composition for hologram recording medium; and x denotes volume contraction rate (%) of composition for hologram recording medium after forming hologram recording layer. <P>COPYRIGHT: (C)2007,JPO&INPIT |
