Using EVA hot melt adhesive film, an epoxy resin prepared photopolymer holographic memory card was prepared, and the preparation process is simple. First, prepared epoxy photopolymer temperature tests were conducted and a new process for the preparation of the holographic storage medium has been proposed. Then, its 532 nm wavelength holographic characteristics were studied. The holographic memory card with a high temperature(≥60 ℃), easy to scratch characteristic diffraction efficiency ≥50%, moderate exposure sensitivity, can be angular multiplexing holographic storage. The holographic storage card for long-term storage tests has been conducted and the cartridge shelf life results ≥ 6 months have been drawn.
