  ABSTRACT: Bragg angle mismatch by tangential and radial tilts is a critical problem in holographic digital data storage. Generally, tangential tilt can be easily compensated for in holographic digital data storage. However, radial tilt is not easily compensated for. In this paper, we propose a new method of radial tilt compensation. The proposed method can compensate for Bragg angle mismatch caused by radial tilt.

  Article: Iterative volumetric ECC schemes for holographic data storage

  ABSTRACT: A new three-dimensional error correction coding (ECC) scheme for holographic data storage, or iterative volu-metric 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.
