ABSTRACT:
In a magnetic ink character recognition (MICR) system, a document bearing magnetizable ink characters is transported past a write station for magnetization preparatory to reading the characters. Each of the ink characters is divided into a plurality of discrete vertical segments; each segment being individually magnetized by a write head in the write station. The velocity at which the document is transported is sensed and time-correlated to the magnetization of each discrete segment to avoid irregularly spaced magnetization due to non-uniformities in transport velocity.
