Iterative volumetric ECC schemes for holographic data storage
A new three-dimensional error correction coding (ECC) scheme for holographic data storage, or iterative volumetric ECC (IVECC), and its decoding algorithm have been developed and evaluated. The IVECC constructs volumetrically coupled ECC blocks, which can correct errors for three dimensions, leading to favorable ECC performance in page-based recording and retrieving system. It also can recover data of seriously corrupted pages or even missing pages by iterative decoding, may occur due to imperfect recording media or other defects on optical devices in holographic data storage.
