Abstract
A pickup carriage drive for a video disc player comprises a selective-activated motor mounted on a pickup carriage. A drive cord is strung between a pair of anchor points disposed in the player, and has a portion wrapped around the output shaft coupled to the drive motor. The motor, when energized, drives the carriage to follow the pickup stylus across the record during playback.
