A Dynamic Measurement Method for Head-Disc Spacing Using Magnetic Head of Disc File Itself as Transducer

本文提出了用磁盘存储器自身的读写磁头作传感器的头-盘间距动态测试方法,并给出了确保方法可靠的关键条件和最优记录位间距。在此基础上,介绍了实际的测试系统和对应于最佳记录位间距的记录频率的确定方法。

A dynamic measurement method for head-disc spacing using magnetichead of disc file itself as transducer is described in this paper. The key conditions to make the method reliable and the optimum recording bit length are obtained. Based on these, a practical measurement system is introduced and a procedure used to determine the optimum recording frequency corresponding to the optimum recording bit length is presented.
