基于光盘质量的动态自适应技术的设计与实现

Design of Dynamic Self-adaptive Technology and the Realization Based on the Disc Quality

采用动态自适应技术来根据光盘质量对主轴转速作自适应的调整 ,以最佳的速度读取光盘数据 ,有利于数据的顺利读取和保护光头组件 .相应地针对光盘反射信号的质量提出了一种间接评估数据质量的方法 ,设计了基于光盘质量的动态自适应技术 ,并应用于高速光盘驱动器伺服控制系统中 .

In this paper, dynamic self adaptive technology is employed to regulate the spindle motor speed according to the different quality of the discs, and it guarantees the read process keeping the optimal speed. This will be more suitable for reading data and protecting the optical head components. An indirect method to evaluate the quality of the disc data and a dynamic self adaptive technology based on disc quality are presented and are applied to the servo system of CD ROM driver system with high speed.
