Abstract
The invention relates to a system for reading data stored on an information carrier. The system comprises a waveguide (1203) which allows displacing laterally the different components in exploiting the reflection of the light beams between a first surface (1207) and a second surface (1208) of said wave guide (1203). Use: Optical storage.
