Answer:

What is Group Coded Recording mean?

In computer science, group coded recording or group code recording (GCR) refers to several distinct but related encoding methods for magnetic media. The first, used in 6250 bpi magnetic tape since 1973, is an error-correcting code combined with a run length limited (RLL) encoding scheme, belonging into the group of modulation codes. The others are different mainframe hard disk as well as floppy disk encoding methods used in some microcomputers until the late 1980s. GCR is a modified form of a NRZI code, but necessarily with a higher transition density.
