Abstract

Information words are stored along rows in a three-dimensional magnetic core matrix. In each row, the cores in position B...G store applied information. The core in position A is set to 1 or 0 in accordance with whether or not a word is stored in the row.

Data Storage System

Information words are stored along rows in a three-dimensional magnetic core matrix. In each row, the cores in position B...G store applied information. The core in position A is set to 1 or 0 in accordance with whether or not a word is stored in the row.

When information is applied, column scanning ring 1 scans the position A cores in the bottom row from left to right. When a core set to 0 is detected, the column scanning control device 2 is set to select the column in which this core is situated. The row scanning ring 3 scans the position A cores in the selected column in response to a pulse generated in output circuit 5.

The selected column is scanned from the top downwards and, when a core set to 0 is detected, a pulse generated in the output circuit 5 is applied to gate 6. Gate 6 then allows input information to be applied to input circuit 7 from which it is fed into the matrix at the location selected by the scanning rings.
