ABSTRACT:
A system for playing back prerecorded signals from a spirally-grooved and rotatable record includes a carriage mounted for lateral motion relative to a motorboard of the system in correlation with lateral motion of a groove-riding stylus during playback. A stylus arm cartridge, enclosing a stylus arm supporting a stylus at one end thereof, is subject to reception in a compartment provided in the carriage. The second end of the stylus arm is pivoted in the cartridge. A first end of a leaf spring, provided for urging the stylus into the record groove during playback, is secured to the stylus. A second end of the leaf spring is secured to a ball which is friction loaded into a socket provided in the cartridge. Adjustment of angular orientation of the ball in the socket provides control of the stylus/record tracking pressure, and the lateral position of the stylus arm in the cartridge.
