磁盘记录系统特性的设计和评价是磁盘驱动器开发中最基本、最重要的课题之一。近年来,随着一系列新型测试仪器的问世,特别像激光多普勒干涉仪(Leser doppler interferometer)和相位裕度分析仪(phase maring analyzer)的出现给驱动器的研制工作提供了强有力的工具,对驱动器的各个组成如头/盘界面、读写通道,定位系统以及精密机械结构等有了更精确的分析手段。在磁盘标准化中,规定了不同位密度下头/盘界面的机、电、磁参数。本文从磁盘驱动器设计的角度叙述了系统记录特性与磁盘标准中若干参数的相互关系。
The design and evaluation of the characteristics of disk recording system is one of the most basic and important issues in the development of disk drives. In recent years, with the advent of a series of new test instruments, the advent of special Leser doppler interferometers and phase maring analyzers has provided a powerful tool for the development of drivers , The driver’s various components such as head / disk interface, read and write channels, positioning systems and precision mechanical structures have a more accurate analysis. In the disk standardization, the provisions of different bit-density head / disk interface, electrical, magnetic parameters. This paper describes the relationship between the system logging features and several parameters in the disk standard from the perspective of disk drive design.
