| 摘要 |
An optical head drive device for driving an optical head in a tracking direction and a focusing direction, comprising a pair of first tracking leaf spring members provided such that the respective one end sides are fixed to a fixing member, and structured to be elastically deformable to the tracking direction on a basis of the fixing section as a base end, a pair of second tracking leaf spring members provided such that the respective one end sides are coupled to the optical head, having substantially the same spring effective length and spring constant as the first tracking leaf spring member, and structured to be elastically deformable to the tracking direction, and coupling members for coupling the respective other end sides of the first tracking leaf spring members and the second tracking leaf spring members.
