Abstract
PURPOSE: A ensure the smooth shift of the tone arm as well as simplify the circuit constitution, by supplying the outputs of both the deflected angle detecting means and the linear shift velocity detecting means of the tone arm of the linear tracking type using the linear motor to the driving circuit of the linear motor.
CONSTITUTION: When horizontal rotary shaft 7 of the tone arm has an angle deflection, the output according to the difference of the light receiving amount between photodetectors 76 and 77 is extracted out of operational amplifier 94 to be supplied to one input side of operational amplifier 88. In other words, the bias voltage is applied to the input terminal of one side of amplifier 88, and thus linear motor 28 is driven. As a result, the tone arm is shifted via the carriage. Furthermore, the above-mentioned bias voltage is piled onto the output of coil 38 of motional feedback control linear shift detector 36 of motor 28 and then applied to the input terminal of one side of amplifier 88. As a result, the smooth compensating shift is secured for the deflected angle of the tone arm, at the same time simplifying the circuit constitution.
