摘要： An electrostatic actuator and a method of driving the same are provided. The actuator controls the displacement of a target object by adjusting a voltage between fixed comb electrodes and a moving comb electrode. The actuator includes an actuator control signal generator generating an actuator control signal by pulse-width modulating an actuator driving signal and a carrier signal; and an actuator unit including the fixed comb electrodes and the moving comb electrode and adjusting the voltage according to the actuator control signal. Accordingly, the displacement can be easily controlled using the pulse-width-modulated actuator driving signal even when both the voltage of the actuator driving signal and the frequency of the carrier signal are high.

摘要： A probe position error detecting method and apparatus in a probe-based data storage system are provided. The method includes preparing servo codes, which are Gray codes. The Gray codes have a Hamming distance of 1 and satisfy alternate conditions for Q (a natural number) and Q+1, the conditions being based on the numbers of “1” bits of codewords of the Gray codes. The method further includes detecting a probe position error from a signal read by a servo probe when the servo probe consecutively scans “1” bits of codewords of the servo codes when tracking. The apparatus includes: a plurality of servo probes; a tracking condition checker; a plurality of position error detectors that correspond to the plurality of servo probes, respectively; and an average position error calculator. Probe position errors are be detected with a stable noise characteristic using fewer probes.
