1 引言作为可录光盘CD-R的升级产品,DVD可录光盘(DVD-R及DVD+R,简为DVDR) 的市场份额迅速上升。不久将来,DVDR光盘必将成为大批量复制生产的标准可记录存储媒体。因而盘片复制商、生产线制造商、测试设备提供商都越来越关注DVDR光盘。二者在记录、读取原理上近似,日趋完善的CD-R光盘复制工艺为DVDR光盘生产提供了坚实的技术基础。下面简单介绍DVD-R光盘技术。 DVD-R光盘规格书中定义了单面单层和双面双层结构。单面的DVD-R光盘是由厚度为0.6毫米的记录层
1 Introduction The market share of DVD recordable discs (DVD-Rs and DVD + Rs, abbreviated DVDRs) is rapidly rising as an upgrade to compact disc CD-Rs. In the near future, DVDR discs will surely become the standard recordable storage medium for high-volume reproduction. As a result, disc duplicators, line makers and test equipment providers are increasingly concerned about DVDR discs. Both in the record, read the principle of approximation, the increasingly sophisticated CD-R disc replication process for the production of DVDR discs provide a solid technical foundation. The following brief DVD-R disc technology. The DVD-R disc specification defines single-sided and double-sided double-sided structures. A single-sided DVD-R disc is made of a recording layer having a thickness of 0.6 mm
