全息存储中的纠错码研究综述
A survey of error correction codes in holographic storage
摘要
Abstract
In the era of big data,the demand for high-density and large-capacity storage technology is increasing day by day.Unlike traditional storage technologies that record data bit by bit,holographic storage uses two-dimensional data pages as the unit for reading and writing,adopting a three-dimensional volume storage mode.With advantages such as high storage density,fast data conversion rate,energy efficiency,safety,and ultra-long-term preservation,holographic storage is expected to become the strong competitor for mass cold data storage.This paper focuses on phase-modulated collinear holo-graphic storage and analyzes the current research status of error correction codes for holographic stor-age.A detailed introduction is provided to an reference beam-assisted low-density parity-check(LDPC)code scheme.关键词
