<p>The invention relates to a reflective holographic data storage carrier (10). The holographic data storage carrier (10) comprises a photosensitive layer (13), a reflecting layer (11 ) and a quarter-wave plate layer (12) disposed between said photosensitive layer and said reflective layer. Said quarter-wave plate layer is made of a biaxial material wherein nx, ny and nz refractive indices verify : n<SUB>x</SUB>>n<SUB>z</SUB>>n<SUB>y</SUB> and n<SUB>z</SUB>=n<SUB>y</SUB>+N<SUB>z</SUB>(n<SUB>x</SUB>-n<SUB>y</SUB>) where z is a direction perpendicular to said layers and Nz ranges between 0.35 and 0.65.</p>
