PIckup for optical recording media
摘要:
The invention relates to a pickup (1) for optical recording media including a monitor diode (14) for light power feedback, the pickup (1) having an increased efficiency and a reduced number of components, and to an apparatus for reading from and/or writing to optical recording media including such a pickup (1).
According to the invention, a pickup (1) for optical recording media includes a light source (2) for emitting a light beam, a monitor diode (14) for obtaining a light power feedback signal, and an optical element (7) for changing a property of the light beam, wherein the optical element (7) has a surface that is inclined with respect to the optical axis and reflects a part of the light beam towards the monitor diode (14).
