Ⅰ系统考虑应用磁鼓的存储部件,在一般情况下,可看做是一个绕一根轴线旋转的磁性圆筒,在其表面上可以按需要写入和抹去预定的磁脉冲。此装置至少应包括以下的主要组件:鼓筒、主轴(包括轴承套筒)、磁头安装壳体、马达、支承板或框架以及外壳。有时候可将两个组件设计成一个整体,以适应系统的特殊要求。鼓筒可用金属或陶瓷(包括玻璃及水晶)制成。在其经过机械加工的外表面上涂覆上磁层,而其内表面别装在与驱动马达相联的可旋转的主轴上。鼓筒被包围在装有磁头的壳体内,而此壳体又和支承板或支承框架牢固地联结在一
System I Consider a storage unit for a drum, which in the general case can be thought of as a magnetic cylinder rotating about an axis on which a predetermined magnetic pulse can be written and erased as needed. This device should include at least the following main components: drum, spindle (including bearing sleeve), head mounting housing, motor, bearing plate or frame, and housing. Sometimes the two components can be designed as a whole, to meet the special requirements of the system. Drums can be made of metal or ceramic (including glass and crystal). The machined outer surface is coated with a magnetic layer and the inner surface is not mounted on a rotatable spindle associated with the drive motor. The drum is enclosed in a magnetic-head-mounted housing, which in turn is rigidly attached to the support plate or support frame at a
