一、前言磁盘驱动器的读写原理是数字磁记录理论中既重要而又抽象的部分。利用磁盘综合性能测试仪,可方便直观地将读写电路各点波形及写电流进行测试、绘图、打印,并计算其各个参数。准确直观地验证了磁记录原理的各结论并为磁盘读写电路的设计提供了精确的依据。 I. INTRODUCTION The principle of disk drive read and write is both important and abstract in digital magnetic recording theory. The use of integrated disk performance tester can be easily and intuitively read and write circuit waveform of each point and write current test, drawing, printing, and calculate its various parameters. Accurately and intuitively verify the conclusions of the principle of magnetic recording and disk reading and writing circuit design provides an accurate basis.
