Abstract
Disclosed is an objective lens driving apparatus having a holder holding an objective lens and connected to a base through at least four linear members such that the holder can be moved both in the focussing direction and in the tracking direction orthogonal to the focussing direction through the flexing of the linear members Undesirable local resonance can be suppressed due to the use of the linear members in support of the holder
