Abstract
An optical head driving mechanism is applied to an optical disc driver that has a base plate, a pair of guide rods and an optical module movably mounted on the guide rods. The driving mechanism includes a base, a movable member, a piezo-actuator and at least a resilient member. The piezo-actuator and the movable member generate proceeding waves at the rim of the piezo-actuator and move the optical module along the guide rods when the piezo-actuator activates.
