Tone arm assembly |
| abstract |
ABSTRACT OF THE DISCLOSURE A tone arm assembly provided with a motor for moving a tone arm in a horizontal direction with respect to a record disc, a servo circuit for keeping the moving velocity of the tone arm constant, and a positioning servo circuit to operate when the tone arm reaches a reproducing position, in which the positioning servo circuit and the volocity controlling servo circuit are combined together thereby to stop the tone arm quickly at a predetermined position. |
