1.前言近来,磁盘介质的制造工艺大有改进,容量超过二亿字节的磁盘存储器已开始实用。为了研制出具有最佳价格-性能比的装置,磁盘的记录密度必须进一步提高。为此,需要获得有关介质特性和可靠性的详细测试数据,同时必须研究新的测试方法或测试系统。普通的磁盘测试装置主要是用作“好、坏”的简单判断,对高密度磁盘介质的测试不适用。因此,作者制造了一台由超小型计算机 1. Introduction Recently, the manufacturing process of disk media has greatly improved, with more than two hundred million bytes of disk storage has become practical. In order to develop a device with the best price-performance ratio, the recording density of the disk must be further increased. To do this, detailed test data on the characteristics and reliability of the medium are required, and new test methods or test systems must be studied. Ordinary disk test device is mainly used as a “good, bad” simple judgment, high-density disk media test does not apply. Therefore, the author made a computer by the ultra-small computer
