* Miller encoding ( also known as Delay encoding or Modified Frequency Modulation, and has variant Modified Miller encoding )

This was made possible as the SuperDrive now utilitized the same MFM ( Modified Frequency Modulation ) encoding scheme used by the IBM PC, yet still retained backward compatibility with Apple's variable-speed zoned CAV scheme and Group Code Recording encoding format, so it could continue to read Macintosh MFS, HFS and Apple II ProDOS formats on 400 / 800K disks.

The hard disk, which used a Modified Frequency Modulation ( MFM ) interface, was a hit, and was later released in a 10-megabyte version, the ST-412 with which Seagate secured a contract as a major OEM supplier for the IBM XT, IBM's first personal computer to contain a hard disk.

Modified Frequency Modulation, commonly MFM, is a run-length limited coding scheme used today to encode the actual data-bits on most floppy disks.

# REDIRECT Modified Frequency Modulation

The earliest and simplest variants were given specific names, such as Modified Frequency Modulation ( MFM ); often, " RLL " refers only to the more complex variants not given such specific names, but that is technically incorrect.

A Modified Frequency Modulation or ( 1, 3 ) RLL encoding stores each data bit as two bits on tape, but since there is guaranteed to be one 0 ( non flux reversal ) bit between any 1 ( flux reversal ) bits then it is possible to store 6, 400 encoded bits per inch on the tape, or 3, 200 data bits per inch.
