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.
作为大数据时代的必然产物，长数据是指在长时间内捕获现实世界变化的大量数据。在这种情况下，人们需要反复使用单个存储设备来记录和读取数 TB 级的数据，且基准线在长达一个世纪的时间内保持不变。在这里，我们通过纳米等离子体混合玻璃复合材料展示了光学长数据存储的概念。通过将纳米棒无烧结地掺入到地球丰富的混合玻璃复合材料中，杨氏模量提高了一到两个数量级。这一发现使得对多种长度的等离子体纳米颗粒的形状控制成为可能，从而实现了超过 10 TB 的连续多级记录和读取，而且在 600 多年的时间内，基准线几乎没有变化，这为影响过去和未来的长数据存储开辟了新的机会。
