Abstract

Emerging as an inevitable outcome of the big data era, long data are the massive amount of data that captures changes in the real world over a long period of time. In this context, recording and reading the data of a few terabytes in a single storage device repeatedly with a century-long unchanged baseline is in high demand. Here, we demonstrate the concept of optical long data memory with nanoplasmonic hybrid glass composites. Through the sintering-free incorporation of nanorods into the earth abundant hybrid glass composite, Young’s modulus is enhanced by one to two orders of magnitude. This discovery, enabling reshaping control of plasmonic nanoparticles of multiple-length allows for continuous multi-level recording and reading with a capacity over 10 terabytes with no appreciable change of the baseline over 600 years, which opens new opportunities for long data memory that affects the past and future.

摘要

作为大数据时代的必然产物，长时数据（long data）是指能够捕捉真实世界长期变化的海量数据集。在此背景下，实现单存储设备中数太字节（terabytes）数据的重复读写，且基线可保持数百年不变的需求日益迫切。本研究提出了基于纳米等离子体混合玻璃复合材料的光学长时数据存储器（optical long data memory）概念。通过将纳米棒无烧结掺入地壳储量丰富的混合玻璃复合材料中，杨氏模量（Young’s modulus）提升了1至2个数量级。该发现通过实现多尺寸等离子体纳米颗粒的形貌调控，可实现存储容量超10太字节的连续多级读写，且600年内基线无明显变化，为面向跨时空的长时数据存储领域开辟了全新发展机遇。
