ABSTRACT:
The present invention relates to an apparatus for writing to optical storage media capable of performing pre-exposure and/or curing of a photo-sensitive material for optical data storage, in particular for holographic data storage.The apparatus has a first light source for emitting a first light beam, a second light source for emitting a second light beam, and a spatial light modulator, which is switchable between at least two states for spatially modulating at least a part of the first light beam, and which is arranged such that in a first state it directs the first light beam towards an optical storage medium, and that in a second state it directs the second light beam towards the optical storage medium.
