Abstract

The invention relates to a holographic data storage device comprising a holographic data storage (HDS) medium, a spatial light modulator (SLM) split up into a plurality of cells. Each cell (K) includes a pattern (Tdata) of data pixels (i) and a reference beam area (Kref). A array (10) of lenses (10K) is disposed substantially at focal distance from said holographic data storage (HDS) medium and said spatial light modulator (SLM), at least one lens (10K) being adapted to capture light from one cell (K) so as to interfere data beams (20k,i)d said reference beam (30K) at a portion (40K) of said holographic data storage (HDS) medium.
