20100020656 | METHOD AND DEVICE FOR SENSITIVITY COMPENSATION - Method and device for generating a control voltage for a position actuator of a disk drive system for displacing a lens of a pick-up unit to a given X-position. The actuator is operated by an open loop control system. First, parameters of the control system are calibrated so that the control system produces a control voltage (Va) from an input position signal (Xact setp). Then, the control voltage is processed in a feed forward system for generating a processed control signal (Va_p) which is fed to the position actuator for displacing said lens to the X-position. A Z-value corresponding to the axial distance of the lens from a calibrated axial position and a temperature of the pick-up unit are measured. The position actuator operates according to the formula: Xdc=Va_p*K(Temp,Z)/(R(Temp)* C(Temp,Z)) in which: Xdc=position signal for said given position Va_p=Va processed K=property of ‘actuator’ | 01-28-2010 |
