Eight To Fourteen Modulation |
(EFM).In magnetic media, a byte commonly has 8 bits.Optical media such a CD-ROM disc uses a 14-bit byte, a modification necessary because of the way data is stored and read with laser, using the pits (indentations) and lands (spaces between indentations) on the disc.In transferring from magnetic to optical media, the 8-bit byte has to be modulated to a 14-bit byte.When the computer reads the CD-ROM, an interface card demodulates the 14- bit optical code back to 8-bit code.
