Optical pick-up having a rotary arm actuator |
摘要 |
A pivoting optical readout device is described in which two folding mirrors ( 121, 122 ) are used in an optical path ( 21 ) between an optical information carrier and a photodetector unit ( 112 ), for rotating a beam of light reflected from the information carrier by 90° such that a push-pull error-tracking signal can be generated.
