[′fāz in′kōd·iŋ]

(computer science)

A method of recording data on magnetic tape in which a logical 1 is defined as the transition from one magnetic polarity to another positioned at the center of the bit cell, and 0 is defined as the transition in the opposite direction, also at the center of the cell. Also known as Manchester coding.

According to the inventors, the very small size of the resolvable spatial element in the hologram (approx 0.01[micro]) is one of the factors which makes the key very difficult to decipher, and is made more difficult by the amplitude phase encoding of the wave.
