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.

Famous quotes containing the words group, code and/or recording:
“There is nothing in the world that I loathe more than group activity, that communal bath where the hairy and slippery mix in a multiplication of mediocrity.”
—Vladimir Nabokov (1899–1977)
“...I had grown up in a world that was dominated by immature age. Not by vigorous immaturity, but by immaturity that was old and tired and prudent, that loved ritual and rubric, and was utterly wanting in curiosity about the new and the strange. Its era has passed away, and the world it made has crumbled around us. Its finest creation, a code of manners, has been ridiculed and discarded.”
—Ellen Glasgow (1873–1945)
“Write while the heat is in you.... The writer who postpones the recording of his thoughts uses an iron which has cooled to burn a hole with. He cannot inflame the minds of his audience.”
—Henry David Thoreau (1817–1862)
