Method and device for reading out the information stored in a storage layer

[Subject] The equipment and the method for reading the information memorized by the storage layer are improved so that a storage layer can be read efficiently and correctly. [Solution means] The present invention uses the receiver 14 for receiving the discharge beam emitted from the storage layer 12, and relates to the equipment and the method for reading the information memorized by the storage layer. The storage layer 12 is supported by the support face 16, and relative motion produces it between the receiver and storage layer in a x direction. A receiver or a storage layer is guided on the guidance sides 11a and 11b and 16 by the guidance means 20a and 20b during generating of relative motion. The interval of the direction of z is adjusted by one support face 16 side by the 1st partial guide, and the interval of the direction of z is adjusted by the 2nd partial guide by the another side side of a support face. The guidance side has been independent of a storage layer, the 1st partial guide 30a and 30c and the 2nd partial guide 30b and 30d are connected mutually, and are 付勢 (ed) mutually in a direction, and it acts on the support face 16 in the shape of pliers.
