Sorry, I can't remember much details. I remember the Amiga had some complicated encoding scheme which was probably called that.

GCR was used on the 1541 and 1571 (except in CP/M mode). See: https://en.wikipedia.org/wiki/Group_coded_recording

Amiga, PC floppies and the 1581 use MFM. See: https://en.wikipedia.org/wiki/Modified_ ... Modulation

AFAIK, GCR uses less overhead.
No one can do everything. Everyone can do something.
