A three-dimensional actuator for compensating disc tilt in slim optical disc drives was developed. The actuator inclines the objedive lens according to the disc tilt in addition to the focus and track-driving directions. The moving part of the actuator has three driving coils and supported by six suspension bars. Its moving coil structure has the advantage to increase the driving sensitivity. The measured driving sensitivities in the focus, trark and tilt directions were 104, 106 m/s^2 V and 1.7°.V, respectively. These values are enough for high speed read-write operation,The result on disc tilt compensation verified the effect of this actuator that the jitter of DVD read-out signal with tilt control was within 10% at 1.0° disc radial tilt.
