摘要
单层BD碟片容量为25GB、双层为50GB,基本上可以满足完全高清节目的记录播放。但是随着3D技术和互动技术的介入以及超大容量数据存储需求的增长,目前的BD标准将面临挑战。本文以工程实践的角度介绍了3种BD碟片的物理结构,并以此为基础,结合当前光存储领域的最新技术,从存储密度和数据传输率两方面展望了BD技术的发展趋势。
The capacity of a single layer BD disc is 25GB.And for dual layer,it is 50GB.The standard can be basically suitable for the FullHD program playing or recording now.But it will be challenged with the development of the 3D's,INTERACTION's and the super large data storage's technology.In this article,we will introducc the BD disc's physical format firstly. Afterward,according to the newest technology of the optical storage,we will give an expectation for the storage density and the data rate of BD disc.
