• Run length limited — or RLL coding is a technique that is used to store data on recordable media. Specifically, RLL prevents long stretches of repeated bits from causing the signal recorded on media to not change for an excessive period, by modulating the data. RLL… …   Wikipedia

• advanced run-length limited encoding —    Abbreviated ARLL. A technique used to store information on a hard disk that increases the capacity of runlength limited (RLL) storage by more than 25 percent and increases the data transfer rate to 9Mbps.    See also RLL encoding …   Dictionary of networking

• Run-length encoding — (RLE) is a very simple form of data compression in which runs of data (that is, sequences in which the same data value occurs in many consecutive data elements) are stored as a single data value and count, rather than as the original run. This is …   Wikipedia

• data-encoding scheme —    The method used by a hard disk controller to store information onto a hard disk or a floppy disk.    Common encoding schemes include the run length limited (RLL) and advanced runlength limited (ARLL) methods.    See also advanced run length… …   Dictionary of networking

• 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
