ABSTRACT:
An apparatus is described for reading a record carrier on which information is stored in an optically readable structure. Between a radiation source and an objective system a mirror system is disposed, by means of which the entrance pupil of the objective lens can be imaged onto beam-controlling elements which deflect the read beam over the information structure.
