Ⅰ.引言为了满足小用户在成本、容量和速度上对外存储器的要求,研制了一种 IBM 1311活盘式磁盘(图1)。该存储装置的功能是在计算机控制信号的控制下选址、写数和读数。为了完成这些操作,该存储装置包括;1)一个液压式的机械选址系统,用来在磁盘表面定出读-写头给定的位置;2)10个读写磁头;3)可换式磁盘组,每组有10个记录磁盘表面(6个磁盘);4)一个带动磁盘组的电动机,它能为液压系统提供动力;5)读写电子线路和控制电子线路;6)磁头
I. INTRODUCTION To meet the needs of small users for external storage at cost, capacity, and speed, an IBM 1311 diskette was developed (Figure 1). The function of this memory device is to locate, write and read under the control of a computer control signal. In order to accomplish these operations, the storage means comprises: 1) a hydraulic mechanical addressing system for setting a given position of the read-write head on the surface of the disk; 2) 10 read / write heads; Disk group, each having 10 recording disk surfaces (6 disks); 4) a motor that drives the disk group, which powers the hydraulic system; 5) read and write electronic and control electronics;
