摘要

A Blu-ray Disc (BD) / Digital Versatile Disc (DVD) / Compact Disc (CD) compatible optical pickup supporting Blu-ray 4x read/write has been developed. To achieve 4x speed for BD, a one-lens-type objective lens was adopted to ensure stability for high-speed tracking servo control. Optical system, signal characteristics, and actuator vibration characteristics of the developed pickup are presented.
