Abstract

PURPOSE: To hold the angle between the stylus tip of a pickup cartridge and a record disk in the best state all the time by supporting an arm without any mechanical contact point except the contact point of the stylus tip with the record disk.
CONSTITUTION: When arm 4 is perfectly at right angles to its tracking direction, the direction of magnetic flux is perfectly in parallel to Hall element 12a, which generates no output. When arm 4 is inclined at angle θ1 to left, Hall element 12a generates the voltage that corresponds to angle θ1 and the voltage flows an electric current to driving coil 11 via the control circuit, so that driving coil 11 will move arm 4 by generating b1-directional force until arm 4 is at right angles to the tracking direction. In addition, arm 4, when inclinded to right, is similarly moved to a correct position.
