ABSTRACT:
The present invention relates to a beam shifting element and to an apparatus for reading from and/or writing to optical storage media using in such a beam shifting element.According to the invention, the beam shifting element has at least a first optical element for deflecting an incoming light beam by a first angle and a second optical element for deflecting the light beam coming from the first optical element by a second angle opposite to the first angle, wherein the first optical element and the second optical element are optical elements with an adjustable deflection angle.
