Method of access to the information contained in a network of the crystalline type by propagation forced of a dipole of dislocation, and the device implementing said method

摘要

A string of bubble domains having a length equal to that of a column portion to be extracted from a bubble domain lattice array is laterally punched into the input side of the array at the height of the desired column portion. As it enters the array it displaces the adjacent and corresponding portion of the first column, which thus becomes a dislocation dipole. The latter is then propagated through the array by subsequent punching cycles until the corresponding portion of the last column is forced out of the array. At this point the dislocation dipole has passed completely through the array, and the corresponding portions of each column have been displaced one column to the right. The process is then repeated until the desired column portion has been displaced across the array into the last column, and then forced out of the array for reading. By punching the forced out column portions back into the array at the input side the original storage order of the array can be reestablished.
