高密度数据存储系统PRML技术原理

The principle of PRML used in the high density storage system

部分响应最大似然技术已经在磁存储及光存储领域得到了广泛的应用,并且在第三代蓝光系统中具有广阔的应用前景。本文结合这一技术的基本原理介绍了在高密度数据存储中的应用。

Partial-response maximum-likelihood(PRML) technology has been broadly used in current magnetic and optical recording systems,and shows great potential to be applied in the third-generation optical disc systems using blue lasers.In this paper,the basic principle of PRML scheme is introduced.
