Abstract
In an era of data explosion, optical data storage provides an alternative solution for cold data storage due to its energy-saving and cost-effective features. However, its data density is still insufficient for zettabyte-scale cold data storage. Here, a coded aperture-based compressive data page with a compression ratio of ≤0.125 is proposed. Based on two frameworks—weighted nuclear norm minimization (WNNM) and alternating direction method of multipliers (ADMM)—the decoded quality of the compressive data page is ensured by utilizing sparsity priors. In experiments, compressive data pages of a monochromatic photo-array, full-color photo, and dynamic video are accurately decoded.
