    • A data recording and readback subsystem for digital computer systems employing random access electron beam memories having an electron beam write/read apparatus for recording data to be stored on a recording member that is subject to fatigue in the eventuality of excessive write/read storage operations at any given physical location on the recording member. The improved method and apparatus for data management comprising systematically permuting the physical location of data stored on the recording member, recording each permutation of the data, deriving signals representative of the number of permutation operations, and combining programmer initiated requests from the computer system central processing unit for data stored in the electron beam memory with the signals representative of the number of permutations to derive an actual physical address signal for application to the electron beam memory for recovery of the requested data.
    • 一种用于数字计算机系统的数据记录和回读子系统,其采用具有电子束写入/读取装置的随机存取电子束存储器,用于记录要存储在记录部件上的数据,该记录部件在可能存在过度写/读存储操作的情况下经受疲劳 录音成员上任何给定的物理位置。 用于数据管理的改进方法和装置包括系统地置换存储在记录构件上的数据的物理位置,记录数据的每个置换,导出表示置换操作次数的信号,以及将来自计算机系统中央处理的程序员发起的请求 存储在电子束存储器中的数据的单元,其具有表示排列数量的信号,以导出用于应用于电子束存储器的实际物理地址信号,用于恢复所请求的数据。
