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