一、前言盒式磁带机因其体积小而轻,操作简单等优点。因而作为数据通信用终端装置、机床控制装置。会计机、小型计算机及微处理机等外存貯装置而广泛使用,随着我国科学技术事业的飞速发展和四个现代化的实现,这种小磁带机必须在我国国民经济各个部门得到更广泛的应用。由于“四人帮”的干扰破坏,我国目前还没有成批生产质量较高的盒式磁带机。因此,对盒式磁带机的读写电路,我们只是在校简易的盒式磁带录音机上作了初步实验,探索了一下调相制电路实现的可售性。写入电路和读出电路主要依据日本MT6盒式磁带机的线路用国产器件作了一些实验,实验作的还很不充分,线路也不成熟,现对作过的实验作一简单总结,和大家共同讨论。望多批评指正。整个电 First, the preface Because of its small size and light weight, simple operation and other advantages. Therefore, it is used as a data communication terminal device and a machine tool control device. Accounting machines, small computers and microprocessors and other external storage devices and widely used, with the rapid development of science and technology in China and the realization of the four modernizations, this small tape drive must be in our country’s various sectors of the economy have been more extensive application. Due to the interference and destruction of the “gang of four,” there are not mass-produced cassette tape-making machines in mass production in our country. Therefore, the tape drive read and write circuits, we just in the school tape recorder simple beginner experiments to explore the phase modulation circuit to achieve the salability. Written circuit and readout circuit mainly based on the Japanese MT6 cassette tape drive made some experiments with domestic devices, the experiment is still inadequate, the line is not mature, now made a simple summary of the experiment, and We discuss together. Hope more criticism correct. The whole electricity
