Abstract: Holographic data storage is a new optical technology which allows storing an important number of bits in a recording material. In this work, two different types of modulations, defocused binary intensity modulation and phase modulation, are compared to obtain which modulation could be the most suitable for holographic data storage. The best modulation would be the modulation with a homogeneous distribution of energy in the FT plane with no zero frequency peak.
