* Der Tangentialtonarm führt den Tonabnehmer radial auf die Plattenmitte zu. Dies im Gegensatz zum Drehtonarm, der den Tonabnehmer in einem Kreisbogen drehend über die Schallplatte bewegt.  
+
* 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.  
* Der Tangentialtonarm tastet die Rille unter den gleichen Bedingungen ab, wie sie der Schneidstichel bei der Aufnahme geschnitten hat. Er bildet somit keinen tangentialen Fehlwinkel und verhindert die als Skating bezeichnete Kraftkomponente.
+
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.
* Beim System Aiwa wird der Tangentialtonarm elektrisch über eine Gewindespindel über die Schallplatte geleitet. Er ist auf einer waagerecht hinter dem Plattenteller angeordneten Führung gelagert.  
+
* 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.  
* Die Steuerung der Bewegung erfolgt elektronisch durch eine im Tonkopf angeordnete "Kenneinheit", die aus einer Infrarot-Leuchtdiode und einem Fototransistor besteht. Sie stellt fest, ob sich eine Schallplatte auf dem Plattenteller befindet, erkennt die Abschnitte zwischen den einzelnen Musikstücken und ermittelt den jeweiligen Aufsetzpunkt der Nadel auf die Platte.

* 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.
* Die Nachsteuerung des Tonarms entsprechend der Rillensteigung erfolgt durch ein fotoelektrisches System am Tonarmlager, das schon bei einer seitlichen Tonarmauslenkung von nur 1/4° den Tonarm nachführt. * Der vom Tonarm und dem Plattenradius gebildete Winkel von 90° wird praktisch eingehalten, so dass der tangentiale Fehlwinkel unbedeutend klein bleibt.
+
* 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.

Remarks[edit]

  • 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.
