Introduced: September 1968
Full Title
Full titles differ between systems:
IPC:
Recording by magnetisation or demagnetisation of a record carrier; Reproducing by magnetic means; Record carriers therefor > Processes or apparatus specially adapted for manufacturing record carriers
CPC:
Recording by magnetisation or demagnetisation of a record carrier; Reproducing by magnetic means; Record carriers therefor (G11B11/00 take precedence) > Processes or apparatus specially adapted for manufacturing record carriers
Of 11 combined children, 7 exist in both systems.
4 codes are CPC-only extensions.
1 shared codes have differing titles between IPC and CPC.
