Run Length Limited This method of encoding data on hard drives is often used to describe the successor to MFM, although it uses very similar hardware. It exists only on old PC systems.
A hard-disk method of encoding information magnetically that uses a scheme (GCR) to store blocks of data instead of single bits of data. It allows greater storage densities and higher transfer speeds than the other method in use (MFM).
