Optical pickup and optical disc apparatus provided with the same

Abstract

The invention provides an optical disc apparatus which restricts an operation sound generated from an objective lens driving portion of an optical pickup and has a reduce sound, in an optical disc apparatus, in particular, an optical disc apparatus installing a microphone for recording an external voice therein. Coils (), a magnet () and opposing surfaces of a yoke () are respectively arranged at substantially point symmetrical positions with respect to an optical axis () of an objective lens () in a state in which no electric current is applied, the yoke () and a unit base () are connected via a spring member (), and the unit base () is mounted to a casing (). In this case, the spring member () is connected at a position () forward apart from the objective lens () with respect to the yoke (), and is formed so as to have at least a deformation freedom in a direction of the optical axis of the objective lens (). The casing () is made in a closed structure surrounding a space in which the unit base (), a lens holder (), the yoke () and the magnet () are arranged, except a surface opposing to a disc-like recording medium ().
