Systems and methods are disclosed relating to electro-mechanical devices and related computer control and audio processing systems intended to optimize playback fidelity of phonograph records. Said recordings are manufactured by a process that employs a cutting head assembly driven in a straight path from the outer to the inner-most radius of the recordable surface. However, most record turntables device that are used to play back phonograph records rely on a stylus transducer attached to the end of a pivoting arm. Instead of the linear path followed by the original cutting head, said tonearm traces an arc across the surface of the recorded disk resulting in playback distortion proportional to error in alignment of said stylus relative to the tangent of the groove. This invention addresses this deficiency and produces an optimal audio quality of playback of phonograph records.
