Modified Frequency Modulation — This article is about Modified Frequency Modulation. For other uses of MFM, see the MFM (disambiguation). Modified Frequency Modulation, commonly MFM, is a line coding scheme used to encode the actual data bits on most floppy disk formats,… … Wikipedia
RLL encoding — An efficient method of storing information on a hard disk. Compared with older, less efficient methods, such as modified frequency modulation encoding (MFM), RLL encoding effectively doubles the storage capacity of a disk. See also advanced … Dictionary of networking

Differential Manchester encoding — Differential Manchester encoding, also called biphase mark code (BMC) or FM1, is a line code in which data and clock signals are combined to form a single 2 level self synchronizing data stream. It is a differential encoding, using the presence… … Wikipedia
8/14 Modulation — Eight to Fourteen Modulation (EFM) bezeichnet das Verfahren, nach dem der Datenstrom, der auf CDs und Minidiscs gespeichert ist, codiert wird. Auch der digitale Sound von Laserdiscs ist EFM codiert. Jedem Byte (Datenblock, bestehend aus 8 Bits),… … Deutsch Wikipedia
Pulse-code modulation — PCM redirects here. For other uses, see PCM (disambiguation). Pulse code modulation (PCM) is a method used to digitally represent sampled analog signals. It is the standard form for digital audio in computers and various Blu ray, Compact Disc and … Wikipedia
Delay encoding — In telecommunications, delay encoding is the encoding of binary data to form a two level signal such that (a) a 0 causes no change of signal level unless it is followed by another 0 in which case a transition to the other level takes place at the … Wikipedia
SuperDrive — is a trademark used by Apple Inc. for two different storage drives: from 1988–1999 to refer to a high density floppy disk drive capable of reading all major 3.5 disk formats; and from 2001 onwards to refer to a combined CD/DVD reader/writer (and… … Wikipedia
