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 (T<SUB>data</SUB>) of data pixels (i) and a reference beam area (K<SUB>ref</SUB>). A array (10) of lenses (10<SUB>K</SUB>) is disposed substantially at focal distance from said holographic data storage (HDS) medium and said spatial light modulator (SLM), at least one lens (10<SUB>K</SUB>) being adapted to capture light from one cell (K) so as to interfere data beams (20<SUB>k,i</SUB>)d said reference beam (30<SUB>K</SUB>) at a portion (40<SUB>K</SUB>) of said holographic data storage (HDS) medium.
