软磁盘驱动器在经过较长时间运行以及磁头等部件更换之后,有必要对磁头、零磁道开关等的位置进行校准。以往的校准方法多数是用专门的校准盘,在联机的方式下进行。但是校准盘的价格较贵,而且对于较小单位,在较少机器的情况下,有时联机调试会出现一定的困难。本人根据近年来的维修实践,在分析磁盘驱动器上控制板线路的基础上,制作了一台十分简单而又实用的校准装置。其原理图如图所示。 It is necessary to calibrate the position of the head, the zero-way switch, etc., after the floppy disk drive has been operated for a long time and the magnetic head components have been replaced. The past, most of the calibration method is to use a special calibration plate, in online mode. However, calibration discs are more expensive, and for smaller units, there may be some difficulties in online commissioning with less machines. Based on the maintenance practice in recent years, I made a very simple and practical calibration device based on the analysis of the control board circuit on the disk drive. The schematic diagram shown.
