BD(Blu-ray Disc)光盘已经在高清电影发行中得到了较普遍的应用,而用于数据存储和备份的蓝光可录光盘的推广也指日可待。多层技术能够有效的提高存储容量,但是随之而来的层间串扰会降低读出信号的信噪比,从而引起抖晃(Jitter)的上升。同时,记录材料的较低灵敏度也限制了高速刻录的可能性。为此,日本佳能(Canon)公司的混合器件开发中心(Hybrid Device Development Center)研究了两种用
Blu-ray Discs (BDs) have gained popularity in high-definition movie distribution, and the promotion of Blu-ray recordable discs for data storage and backup is just around the corner. Multi-layer technology can effectively improve the storage capacity, but the ensuing interlayer crosstalk will reduce the signal-to-noise ratio of the read signal, resulting in jitter rise. At the same time, the lower sensitivity of the recording material also limits the possibility of high-speed recording. To this end, Japan’s Canon’s Hybrid Device Development Center (Hybrid Device Development Center) to study the use of two
