Study on Dual-Lenses Actuator for HD-DVD System

차세대 DVD 시스템용 Actuator 연구

  • Published : 2002.11.01


Recently, an optical disc system has been proposed using blue laser diode, high NA objective lens and groove only disc structure. A new method is needed to readout CD and DVD in the blue system. In order to readout CD and DVD in HD-DVD system, we adopted dual-lenses actuator in consideration of optical utilization efficiency, optical performance and insurance of sufficient W.D (working distance).
