以光儲存的記錄方式,近年來有著急速的進步與成長,其中光學讀寫頭之發展成為重要的關鍵技術之一。本文從碟片容量密度之提昇與多種波長之需求介紹各型光學讀寫頭之演進,進而說明次世代藍光儲存系統之發展現況。
In recent years, the art of optical storage had great progresses and the development of optical pickup heads has been one of the most important key technologies. We reviewed the evolution of various optical pickup heads corresponding to the increasing of disk capacity density and the requirement of multiple wavelengths. Furthermore, the status of next generation blue-laser storage system was also described in this paper.
