In the information explosion era, the demand for high-density stable storage technologies is soaring. Multi-dimensional optical storage with femtosecond laser writing offers a potential solution for massive data storage. However, equipment instability and reduced voxel resolution inevitably lead to data errors. Here, we propose and demonstrate a paradigm exemplifying high-fidelity eternal lifetime optical storage enabled by error correction mechanism. We increase information density by reducing voxel size and spacing. Leveraging deep learning methods, we achieve 8-bit voxel encoding and a storage capacity of 2.15 Tb/disc. We implement the Reed-Solomon(RS) algorithm for errorfree data recovery and get the trade-off between the storage capacity and the redundancy length. Our storage paradigm takes advantage of error-correcting codes, together with permanent information storage capabilities of extremely stable fused silica, marking a significant advancement for recording massive data to the application level and making it possible to faithfully record the information generated in human civilization.
