A magnetic store comprises a plurality of conductors D 1 , D 2 , D 3 &c. coated with rectangular hysteresis loop material b arranged parallel to each other in the troughs of corrugated read/write conductors G 1 , G 2 as shown. Fig. 2 shows one word of a matrix store in which a plurality of read/write conductors are arranged parallel to each other and orthogonal to the conductors D 1 , D 2 , D 3 &C., Fig. 1 (not shown). In order to write information into a word a word current is applied to terminal K 1 on flat conductor R 1 which is connected via connector V 1 , to read/write conductor G 1 , arranged as shown. Current then flows via connector V 2 to a further flat conductor R 2 and thence to a second corrugated read/write conductor G 2 to output terminal K 2 . The current in read/write conductors G 1 , G 2 magnetizes the coated conductors D 1 , D 2 &c. alternately in opposite directions along their axes. Coincidently with this current a current pulse is applied to the copper conductors a of the coated conductors the direction of which determines the information to be stored in each storage position defined by the area of conductor D 1 , D 2 &c. coupled by the read/write conductors. The read/write current is terminated prior to the current in conductors D 1 , D 2 and the resultant magnetization is either clockwise or anticlockwise around the circumference of the coated conductors depending on the binary information stored. In order to read out non-destructively a current is applied to terminal K 1 and voltages are induced in the coated conductors D 1 , D 2 &c., the polarity of which indicates the information stored. The coated wires may be provided with insulation c. |
