using single-aperture storage elements, e.g. ring core; using multi-aperture plates in which each individual aperture forms a storage element

Introduced: September 1968

Full Title

Full titles differ between systems:

IPC:

Digital stores characterised by the use of particular electric or magnetic storage elements; Storage elements therefor > using magnetic elements > using single-aperture storage elements, e.g. ring core; using multi-aperture plates in which each individual aperture forms a storage element

CPC:

Digital stores characterised by the use of particular electric or magnetic storage elements; Storage elements therefor (G11C14/00 - G11C21/00 take precedence) > using magnetic elements > using single-aperture storage elements, e.g. ring core; using multi-aperture plates in which each individual aperture forms a storage element

CPC subdivides this area 3x more granularly than IPC with 3 additional codes.

3 codes are CPC-only extensions.

IPC defines codes here since 1974.
