| Zusammenfassung: | In this paper, a new approach of disk tilt servo by using piezoelectric modal wavefront actuator is
proposed. A compatible configuration of commerical optical pickup head (PUH) is presented with a
piezoelectric folding mirror. Based on this device, the innovation has the advantages of high
bandwidth, linear control, simple drive line and high spatial wavefront resolution. |
