An acronym for Modified Frequency Modulation, an encoding scheme used by PC floppy disk drives and hard drives through the mid-1980s. Several competing schemes, such as RLL (Run Length Limited), produced faster data access speeds and increased a disk's storage capacity by up to 50 percent. This technology was pioneered by Seagate, Tandon and Control Data founders. It is often known as the ST512/406 interface.
