Group Code Recording
In computer science, group code recording (GCR) refers to several distinct but related encoding methods for magnetic media. The first, used in 6250 cpi magnetic tape, is an error-correcting code combined with a run length limited encoding scheme. The others are different floppy disk encoding methods used in some microcomputers until the late 1980s.
