Device and method for reading out information stored in a storage layer
View Patent ↗A device and method for reading out information stored in a storage layer using a receiving device for receiving emission radiation that has been emitted from the storage layer. In this connection 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 that is independent of the storage layer. When guiding the receiving device, the level of the guide surface in a z direction coincides with the level of the support surface in the z direction.
1. Device for reading out information stored in a storage layer, comprising:
a receiving device for receiving emission radiation emitted from the storage layer;
a support surface for supporting the storage layer, wherein an x-y plane is defined by the support surface; and
a guide means for guiding the receiving device on a guide surface during the execution of a relative movement between the receiving device and the storage layer in the x direction, the guide surface being end portions of the support surface and resident within the x-y plane.
2. Device according to claim 1 , wherein the support surface comprises glass.
3. Device according to claim 1 , wherein the guide means comprises a bearing for supporting the receiving device.
4. Device according to claim 3 , wherein the bearing is formed as an air cushion.
5. Device according to claim 4 , wherein the bearing comprises at least two air cushions that form a pair of bearings that are arranged on both sides of the guide surface in a z direction that runs perpendicular to the x-y plane defined by the support surface.
6. Device according to claim 5 , wherein the air cushions of the pair of bearings are connected to one another in a pincer-like manner and are pretensioned against one another.
7. Method for reading out information stored in a storage layer using a receiving device for receiving emission radiation that has been emitted from the storage layer, wherein the storage layer is located within a substrate having a support surface defined by an x-y plane, said method comprising:
a) reception by the receiving device of emission radiation emitted from the storage layer;
b) generation of a relative movement between the receiving device and the storage layer in the x direction; and
c) guidance of the receiving device during the generation of relative movement of using a guide means, on a guide surface defined as end portions of the support surface and resident within x-y plane.
8. A device for reading out information stored in a storage layer, comprising:
a receiving device for receiving emission radiation emitted from the storage layer;
a support surface for supporting the storage layer, wherein an x-y plane is defined by the support surface; and
a guide for guiding the receiving device on a guide surface during the execution of a relative movement between the receiving device and the
storage layer in the x direction, the guide surface being end portions of the support surface and resident within the x-y plane.
9. A device according to claim 8 , wherein the support surface comprises glass.
10. A device according to claim 8 , wherein the guide comprises a bearing for supporting the receiving device.
11. A device according to claim 10 , wherein the bearing is formed as an air cushion.
12. A device according to claim 10 , wherein the bearing comprises at least two air cushions that form a pair of bearings that are arranged on both sides of the guide surface in a z direction that runs perpendicular to the x-y plane defined by the support surface.
13. A device according to claim 12 , wherein the air cushions of the pair of bearings are connected to one another in a pincer-like manner and are pretensioned against one another.
