Abstract
In this invention, an objective lens driving device, an optical pickup, and an optical disk device are disclosed which have a feature that plural dynamic vibration absorbers provided at the retaining section, by which the elastic supporting members supporting the movable section retaining the objective lens are connected to the movable section, can reduce a resonance peak, which may worsen the servo characteristic, and suppress unwanted vibration effectively, since the character frequency of the dynamic vibration absorbers functions as a damper against the vibration of the movable section. This invention also discloses a method of suppressing the vibration of the movable section.
