ABSTRACT:
A reproducing apparatus for a disk-shaped recording medium, wherein a pickup detects signals from a rotating disk-shaped recording medium in contact with the latter. The reproducing apparatus is so constructed that vertical and horizontal movements of the pickup can be selectively made by actuating only one control knob, and that the horizontal movement of the pickup is prevented when the latter is in contact with the disk-shaped recording medium, even if the control knob is erroneously or accidentally actuated.
