Modified Frequency Modulation Frequency Modulation") A modification to the original {frequency modulation} scheme for encoding data on {magnetic disks}. MFM allows more than 1 symbol per flux transition (up to 3), giving greater density of data. It is used with a data rate of between 250-500 kbit/s on industry standard 3.5" and 5.25" low and high density {diskettes}, and up to 5 Mbit/s on {ST-506} {hard disks}. Except for 1.44 MB floppy disks, this encoding is obsolete. Other data encoding schemes include {GCR}, {FM}, {RLL}. See also: {PRML}. (2002-06-24) | |
