Abstract

A device for reading out information stored in a storage layer (10), which facilitates a good reproduction quality of this information stored in the storage layer (10). The device (1) includes a radiation source (2) for emitting stimulation radiation (20). Using this stimulation radiation (20), the storage layer (10) is stimulated to emit an emission radiation that corresponds to the information stored in the storage layer (10). The device (1) further includes a receiving device (3) to receive this emission radiation emitted by the storage layer (10). A distance device (30, 56) for setting a pre-specified distance (28, 59) is located between the receiving device (3) and the storage layer (10). A drive device imparts relative movement in a transport direction (A) between the radiation source (2) and the receiving device (3), on one hand, and the storage layer (10) on the other.
