Abstract

PURPOSE:To avoid locked groove, by almost matching a position of a magnetic pole of a skipper magnet near a cantilever with a center axial line of a pair of skipper coils toward the magnetic pole located at both the sides. CONSTITUTION:A location of a magnetic pole of a skipper magnet 3 near a cantilever 4 is almost matched with a center axial line of skipper coils 1a and 1b, and the position of the skipper magnet 3, the cantilever 4, and a pickup stylus 5 is located almost at the center of the skipper coils 1a and 1b. With the relation of position like this, when an N pole is generated on the skipper coil 1a and an S pole is on the skipper coil 1b, the pickup stylus 5 is lifted up while being slightly turned counterclockwise by taking the rotating fulcrum of the cantilever 4 as a center and jumped into a groove toward the progressing direction, allowing to avoid locked groove.
