A new method of supporting a pickup while reproducing a phonograph record is described. The arrangement permits the pickup to follow along a radial line, thus eliminating tracking error. Static friction is greatly reduced, so that the force required to pull the pickup across the record is small. In addition, the arrangement described here provides mechanical resistance that is effective in a lateral direction, and hence effective in damping tone-arm resonance. The damping is ineffective in a vertical direction, however, so that the pickup readily follows warped records.
