An improved semiconductor laser pickup for an optical PCM audio disk player is described. In order to raise the servo gain, a reduction in the size and weight of the optical system was tried through the use of a newly designed lens and a revised optical path. A unique simplified two-dimensional servo actuator without any spring for suspension was developed.
