DVDR9生产工艺优化与电信号控制(2P工艺)

Process optimizing and electronic signal control of DVDR9(2P Process)

1.引言 双层DVDR(DVD±R9),自问世之初,就倍受 关注,其8．5G的容量,大大刺激了复制厂家和消费者 的胃口,其发展速度之快,令人惊叹。在HD-DVD和 Blu-ray进入市场之前,DVDR9是存储容量最大的载 体之一,而且目前刻录机市场上几乎所有的DVDR刻 录机都与DVDR9兼容,其前景无疑令人看好。

A disc format, whatever the kind, must be up against three problems before approaching the market: realizable read/write theory; stable, low-cost and large-duty replication process; comprehensive inspection technology. Here is an overview of process optimizing and electrical quality control for dual layer DVDR of 2P process. In next issue, we will discuss the IS process.
