Sony PS-FL77

2-speed, fully automatic, front loading turntable featuring a biotracer/linear tracking tonearm system (1983)

Description

A linear tracking tonearm is designed to duplicate the movement of the head which cuts the record master. Compared with a pivoted arm, a linear tracking arm has a very small tracking error (which means greatly reduced harmonic distortion) and almost no pressure on the inside wall of the groove (which means improved tracking ability and channel separation).

The horizontal and vertical movement of the tonearm is monitored by the Biotracer's own sensors, and this information is transmitted to the tonearm by the tonearm's own linear motors to suppress resonance at low frequencies and to obtain the maximum signal to noise ratio.
