Magnetic Memory Using Chips

Folded magnetic strips 1 are stored in a storage member. Strips 1 are selectively accessed for reading and writing magnetic data stored on the inside surfaces of the fold.

The chip is a piece of compliant material folded in half to make a double thickness. A number of such double chips are contained in the storage container. For access, both ends of the storage container are removed as it is indexed. Pusher 2 starts the strip into a pair of feed rolls. Separator 3, such as an air blast, directs the leaves of the chip to either side of rotary cylinder 4. The feed rolls continue feeding the leaves between cylinder 4 and guides 5 and 6 to a stop 7. This is located 180 degrees away from the entry. Orifices in the guides cause a compliant contact between the magnetic surfaces of the chip and cylinder 4. Magnetic read-write heads 8 or 9 are situated in the rotating cylinder so that they come into contact with the chip magnetic surface. The chip is returned to the cell by reversing the feed rolls and using the pusher to make the final retraction of the chip into the cell.
