一、引言 数字磁带机由于数据存贮量大,使用方便、磁带保存简单及性能可靠等优点,在整个计算机系统中应用很广。随着电子计算机的高速化、大型化,数据量增加,使用磁带更加频繁。为了减轻装卸带盘的工作量和提高效率,近年来,国外许多厂家都生产了具有自动装带功能的磁带机。参照国外的经验,我们研制了ZDC-206型磁带机。该机具有自动装带功能,其面板部分结构如图1所示。按照本机的逻辑程序,它能自动地将文件盘上的磁带穿过通
I. INTRODUCTION Due to the advantages of large data storage, easy to use, simple tape storage and reliable performance, digital tape drive is widely used in the whole computer system. With the high-speed computer, large-scale, increasing the amount of data, the use of tape more frequently. In order to reduce the workload of loading and unloading reels and improve efficiency, in recent years, many foreign manufacturers have produced a tape drive with automatic loading function. Reference to foreign experience, we developed a ZDC-206 tape drive. The machine has automatic loading function, the panel part of the structure shown in Figure 1. According to the native logic program, it can automatically pass the tape through the file tray
