Abstract
Disclosed are an optical system driving device, for preventing the unwanted vibration of an elastic member supporting a holder on which an object lens is mounted, as well as resolving a resonance frequency problem and for increasing manufacturing efficiency and reducing the number of parts required, and an optical recording apparatus incorporating such an optical system driving device. The optical system driving device includes a holder holding an optical element; support means for supporting the holder and permitting its displacement in a focusing direction; a carriage mounting the holder and the support means moving in a tracking direction; drive coils included in the holder for displacing the holder in the focusing direction; and a flexible printed board supplying a drive current to the drive coils. The support means includes a fixed portion and an elastic member, one end of which is fixed to the fixed portion and the other end of which is connected to the holder. Further, a vibration damping member, connected to the fixed portion, is mounted on the side of the elastic member and is sandwiched between the flexible printed board and the elastic member.
