Read/ write channel is the circuit that between the read/ write head and interface controller, it is an important ingredient of the digital information storage system. 硬盘读/写通道是介于读/写头与设备控制器之间的电子电路,它是数字信息存储系统中数据通道的重要组成部分。
The read/ write channel, as an important component of hard disc, whose key functions are to fulfill data writing into storage and reliable data recovery through circuit. 读写通道是硬盘的重要组成部分,其关键的功能是通过电路实现数据可靠的写入和读出。
The early technology used in read/ write channel is peak detection, magnetic record density has been increased significantly as a result of the application of partial-response maximum-likelihood. 早期的读/写通道基于峰点检测技术,之后部分响应最大似然通道技术的应用显著地提高了记录密度。
