Abstract
A magnetic printer includes an elongated comb-like printing head disposed opposite a magnetizable-oxide-bearing surface of a selectively magnetizable moving belt, and adapted to magnetize regions of the belt in a direction transverse to the direction of belt movement; and a magnetic brush for depositing magnetic ink upon the oxide-bearing remaining surface of the belt, with the magnetic brush positioned beneath the printing head, whereby the printing head provides a bearing surface along which the magnetic belt slides. The brush is designed for minimum field at the inking position while the head is designed to have its field direction transverse to the direction of the field of the brush, for minimum field interaction.
