Abstract

PURPOSE: To improve the stop position precision of a tone arm by providing a stop- position setter for the tone arm with a moving member, linear motor index member, driving method driving and stopping it, detecting method for relative position deviation between the above-mentioned members, etc.
CONSTITUTION: When tone arm 1 is in play mode and lead-in mode, the current movement direction is assumed to be positive and when in return mode, it is considered to be negative; and the 1st element 13a is used to detect relative positions of moving member 4 and index member 18 in the positive direction, and the 2nd element 13b to detect relative position deviation between members 4 and 18 in the negative direction. In thid case, when index member 18 moves in the positive direction, for example, the quantity of light received by element 13a exceeds that by element 13b and an output equivalent to the relative position deviation is supplied to comparing circuit 19. Consequently, member 4 follows up the movement of member 18 with precision.
