Abstract

We introduce advanced servo techniques for optical disk drives. High speed and precise optcal beam-positioning and following controls are required archival memories such as high density and high data transfer rate optical disk drives for recording many data and high quality moving pictures toward next generation systems. The zero phase error tracking-feed-forward (ZPET-FF) control method is effective for the next generation systems, which have high disk rotation speed beyond the limit of 10,000 rpm of optical disk drives such as current CDs, DVDs or Blu-ray discs.
