Abstract
A card changeable permanent magnet twistor memory element of improved characteristics has been designed. The desired characteristics were obtained by:
-
(1)
Halving the solenoid width to enhance the drive field.
-
(2)
Replacing the copper return wire in the twistor pair with a reverse wrapped twistor wire.
-
(3)
Installing a Permalloy sheet between the word solenoid and the solenoid board to reduce interaction fields within the memory.
-
(4)
Annealing the twistor wire to lower the coercive force and to increase the squareness ratio of the moly-Permalloy tape.
