ABSTRACT:
For any selected total number of scanning heads and a required minimum spacing between the scanning heads, the scanning heads are arranged in one or more arrays to read or write substantially parallel lines on a medium or surface at closer distances than the center to center distance of adjacent scanning heads in the indexing direction. The scanning heads in any array do not have to be spaced uniform distances from each other. When the scanning heads are arranged in more than one array, each of the arrays is spaced an arbitrary distance from the adjacent array in the pass direction. To arrange the scanning heads for interlace scanning, they are initially arranged in a single line in the indexing direction with their centers spaced from each other the same distance as the centers of the parallel lines, which are being read or written. Then, some of the scanning heads are shifted in at least one of the pass and indexing directions with any shifting in the indexing direction being a pitch distance or a multiple thereof.
