Method and apparatus for forming magnetic latent images

摘要

A method and apparatus for forming latent images in which all channel heads are used in different line density scanning. In the case of a multi-channel head having at least three channels which are positioned with a constant distance, the order of the arrangement of loci of the respective channels is made to correspond to two normal and reverse sets of line densities, so that recording at two different line densities can be made by one multi-channel head.
