Disclosed is a high-speed dynamic actuating system for optical disks, particularly useful in an optical disk drive, wherein a closed-loop approach is used to overcome the diversity between devices and thus meet the requirement for high speed track-accessing and solve the problems in that the convention open-loop track-jumping takes a long period of time to perform segmental adjustment. The pick-up head is activated by applying high-speed dynamic actuation of the lens so as to conform to the pre-determined velocity curve and eliminate the wobble of the lens caused by different track-jumping times in an optical disk drive and a hard disk. In addition, said system can be implemented in an integrated circuit (IC), which is directly controlled by the hardware and thus effectively simplifies the complicated configuration as in the prior art.
