Abstract: A device and method for reading out information stored in a storage layer using a receiving device. The storage layer is supported on a support surface that is defined by an x-y plane and a relative movement is generated between the receiving device and the storage layer in the x direction. The receiving device or the storage layer is guided during the generation of the relative movement by a guide system on a guide surface. Using first and second partial guides, an interspacing is adjusted in a z direction that lies perpendicular to the x-y plane, on either side—viewed in the z direction—of the support surface. The guide surface is independent of the storage layer and the first and second partial guides are connected to one another and are pretensioned against one another, and act in a pincer-like manner on the support surface.
