Tone arm holder

The tone arm holder includes a saddle with a hook portion that defines an open end. A resilient dividing member is located on the top surface of the saddle. The space between the resilient dividing member and the hook define a lock seat configured and arranged for frictional engagement, receipt and storage of a tone arm therein. The opposing side of the saddle from the resilient member defines a performance seat configured and arranged for freely supporting a tone arm whereby a tone arm may be placed on and removed from the performance seat without frictional engagement of the tone arm to the holder. The tone arm is freely movable between the performance seat at a first position and the lock seat at a second position by traversing across the resilient dividing member by exceeding the resilient force of the resilient dividing member.

APPARATUS, METHODS, AND SYSTEMS FOR CONTROLLING TONEARM TRACKING FOR A RECORD TURNTABLE
20180247670 · 2018-08-30 ·

Apparatus, methods, and systems for use in providing tangential (linear) tracking of a stylus on a record during play. In some embodiments, a tonearm assembly includes a tonearm with a laser emission source mounted thereto, and a receiver for receiving a light beam from the laser emission source and for splitting the light beam, and a movement actuator for adjusting a position of the tonearm based on a differential in light intensity between different portions of the split beam.
