Abstract:
1. An optical head device comprising: a lens holder in which an objective lens and drive coils are mounted; a plurality of elastic support members which support said lens holder to move in a focusing direction and a tracking direction; said lens holder having a coil holding portion for holding said drive coils and a lens holding portion which projects from said coil holding portion to the front to hold said objective lens; and said lens holding portion being formed thinner than said coil holding portion to avoid interference with a deflecting element positioned beneath said lens holding portion, having a flat surface with an arc shape from the side portion to the front along the outer circumference of said objective lens so as to gather vibrations in the focusing direction at a front end portion of the lens holding portion, and having first vibration-absorbing member attached to the front end portion thereof such that an attaching face of the first vibration absorbing member is formed in the focusing direction so as to absorb the vibrations in the focusing direction wherein the lens holding portion is formed as a flat surface and includes a wide portion that extends at an equal width from the coil holding portion, and a side portion which inclines inwardly and widely from the border with the wide portion, and a front portion which is shaped to border with the side portion along the outer circumstance of the objective lens.
