Abstract:
A device for driving optical system, comprising:an optical system for focusing light on an optical recording medium and irradiating said optical recording medium with focused light; a holder for holding said optical system; a support member for supporting said holder; a support system including at least six linear elastic bodies having the same length, said linear elastic bodies respectively having one ends fixed to said support member and arranged thereon approximately in a circle, and other ends fixed to said holder and arranged thereon approximately in a circle, to support said holder on said support member; a focusing drive system for driving said holder in a direction of an optical axis of said optical system; a tracking drive system for driving said holder in a radial direction of said optical recording medium; and a tilting drive system for driving said holder in a direction in which rotation moment generates about an axis, said axis being perpendicular to said direction of said optical axis and to said radial direction of said optical recording medium.
