Random Access Magnetic Strip Memory

A memory device provides random access of magnetic strips in two dimensions. Capstan 1, read-write head 2, and take-up reel 3 at A are mounted on platform 4 shown at B for movement in directions indicated by arrows 5 and 6 above storage cells. These are arranged in a matrix shown at C.

Reel 3 has an associated leader 7 shown at D that moves in a guide 8 at E. Guide 8 is formed of two portions 8a and 8b arranged for gripping and releasing action as indicated by arrows 9a and 9b, and 10a and 10b.

In order to read or record on a particular magnetic strip, platform 4 is first moved in a direction to position leader 7 above the desired cell. Guide 8 is contracted so that leader 7 grips the top portion 11a of a strip 11 such as that shown at F. Strip 11 is pulled past head 2 by drive devices, not shown. When processing is completed, it is returned to its cell at which time guide 8 releases leader 7.
