Remarks

• The tangential tonearm guides the pickup radially towards the center of the record. This in contrast to the rotary tonearm, which moves the pickup in a circular arc rotating over the record.

The tangential tonearm scans the groove under the same conditions as the stylus cut it during recording. It therefore does not form a tangential skew angle and prevents the force component known as skating.

• In the Aiwa system, the tangential tone arm is electrically guided over the record by a threaded spindle. It is mounted on a guide arranged horizontally behind the turntable.
• The movement is controlled electronically by an "identification unit" located in the sound head, which consists of an infrared light-emitting diode and a phototransistor. It determines whether a record is on the turntable, detects the sections between the individual pieces of music and determines the respective point of contact of the needle with the record.
• The tracking of the tonearm according to the groove pitch is done by a photoelectric system at the tonearm bearing, which already tracks the tonearm at a lateral tonearm deflection of only 1/4°. The angle of 90° formed by the tonearm and the plate radius is practically maintained, so that the tangential misalignment angle remains insignificantly small.
