Method and device for performing tilt correction using multi-dimensional actuator

The invention relates to for inclination angle control method and device. With focusing and inclination angle control output, and is the substrate of the differential of the focus control of the disc (1) with different radius for determined the radial direction inclination angle value control light recording/focusing and inclination angle state of reproduction light beam. The combination for example the three-dimensional implementing performing mechanism and dz/dr obliquity measurement capable of the following advantages: Realizing focusing and inclination angle adjusting the identity element. Optical any of the; a fan to of the influence a or a measuring change of the environment conditional and/or the circuit is that is minimum, so reducing compensation claim. Then, which are interconnected to tap's coil device three-dimensional implementing performing mechanism (11) connected with the three-dimensional focal point adjustment. The automatic, which is a three-dimensional implementing performing mechanism is provided with a displacement or the error is the forward feeding inclination angle compensation, and a is needed one additional the sensor.
