在计算机上使用的数据磁带是要在各台磁带机之间频繁地交换使用的。因此,作为磁带互换的前提,要求在某一台磁带机上写入的数据带,装到其他磁带机上都能正确无误地读出。为了保证这种互换性,就需要检查、调整磁带机写入、读出时所产生的各道信息写入位置和读出时间的差异。由此引出了用一“偏斜校正标准带”作为基准调整磁带以消除这种差异的方法。这里介绍的内容是有关偏斜校正标准带的制作原理和值得注意的几个问题。
Data tapes used on computers are frequently exchanged between tape drives. Therefore, as a prerequisite for the exchange of tapes, data tapes written on one tape drive are required to be read correctly on other tape drives. In order to ensure this interchangeability, you need to check, adjust the tape drive to write, read out the information generated when the location of each write and read the difference between the time. As a result, a method of adjusting the magnetic tape with a “skew correction standard tape” as a reference to eliminate such a difference was introduced. The content presented here is about the production principle of skew correction standard tapes and several issues worth noting.
