Abstract

PURPOSE: To eliminate the arm drift and thus ensure a smooth linear shift for the tone arm for the player of the linear tracking type which uses the linear motor, by giving the brake with motional feedback to the turn of the tone arm.
CONSTITUTION: A comparison is given through operational amplifier between the detection output of coil 62 of horizontal rotary vibration detector 72 and the voltage which is applied to coil 63 of horizontal rotary driving motor 71. At the same time, either one of two transistors 97 and 98 is driven selectively with the above comparison output. Thus the forward or backward current flows to coil 63, and motor 71 produces the driving force with which the output of detection coil 62 becomes zero. This force functions to give the brake to the turn of tone arm 5 and centering on horizontal rotary shaft 7. As a result, the drift can be eliminated for arm 5 which performs the linear tracking, thus ensuring a smooth linear shift in the horizontal direction.
