Abstract

A data page for use in a holographic data storage system, and to a method and an apparatus for writing to holographic storage media using such a data page are described. The data page has dark zones for each boundary between phase blocks of a phase mask of the holographic data storage system, which consist of switched-off pixels that are not used for encoding data, and which coincide with the boundaries between the phase blocks.
