摘　　要：光驱系统不断集成各种光处理模块以兼容各种碟片,兼容度的提高及市场上光盘碟片介质种类的增多,给光盘介质类型的识别带来了困难.文章提出一种高效识别光盘介质类型的方法,并给出详细实现过程.测试结果表明该方法可以在光驱启动时高效快速地识别出碟片介质类型,从而快速设置OPU激光功率,通道参数和伺服工作参数,使光驱能够更快的启动并读取对应碟片上的数据.Optical driver will-integrate all kinds of module for dealing with CD, DVD, HD and BD disc. With the compatibility improving and the optical disc type having gone up, it is difficult to ascertain all kinds of Optical Disc. This paper proposes a high efficient method of ascertaining the format of a loaded optical disc, and provides the processing of implement. Testing resuits show that this method can make optical driver discriminate the optical disc type efficiently and set OPU power, channel parameters and servo parameters, thereby booting and reading the data on a loaded optical disc rapidly.
