Optical record carrier reading and/or writing apparatus, has reflector formed at edge region of optical element arranged in beam path of optical diode

摘要

The apparatus has an optical element (4), such as an anamorphotic prism, in the beam path of light from a laser diode (2), and a reflector for outputting part of the light to a photodiode (16) arranged outside the beam path. The reflector is a sub-region, preferably the edge region, of the light incidence surface (8) of the optical element.
