Abstract

The available information which is sharply increased requires a long time-period and high-capacity preservation method. In this paper, we proposed a method to preserve miniature image in stack structure. A large number of information images with a minimum pixel size of 200 nm were transferred to an AIST thin film using a laser directly writing system. After clearness, the information region was retained and the non-information region was removed. The single-layer information region samples with a thickness of 0.15 mm have high contrast and high transmittance. After being stacked and packaged into a 52-layer structure, each layer information image can be read out directly by an optical microscopy. The tolerance of the material to acid, alkali, and temperature is tested, and the results show that this method has excellent information preservation performance. This work provides a promising solution for future information preservation.
