Abstract

PURPOSE: To vibrate a pickup in a tracking direction by preventing the generation of parasitic oscillation by applying the pickup with a couple of forces by driving device provided at upper and lower symmetric positions centering on a pickup fulcrum.
CONSTITUTION: Semiconductor laser pickup 1 held by support member 2 vibrates right and left on coupling piece 2C, formed of the elastic material of member 2, as a fulcrum. Centering on this coupling piece 2C, driving parts 10 and 11 only for the tracking direction that have movable pole 17, magnetic 18, etc., provided through electromagnetic coil 13 are provided at upper and lower symmetric positions and pickup 1 is applied with a couple of forces from driving parts 10 and 11. Therefore, the generation of harmful parasitic oscillation is prevented and pickup 1 vibrates excellently in the tracking direction, thereby attaining tracking.
