Abstract
Apparatus for producing a preselected final image in a travelling magnetic image-storage medium, which image is formed of an arrangement of individual magnetic image units and line segments formed of a plurality of linearly disposed contiguous units having a predetermined center-to-center spacing. Adjacent units in adjacent line segments have substantially the same predetermined center-to-center spacing when viewed in a direction substantially normal to the direction of travel, and also have a known maximum actual center-to-center spacing. Plural magnetic writing heads, each capable of producing an image unit, are distributed to have, when viewed in a direction substantially parallel with the direction of travel of the medium, a center-to-center spacing equalling that of contiguous units in a line segment. The actual center-to-center spacing between heads capable of forming adjacent image units in a line segment exceeds the mentioned center-to-center spacings between adjacent units. A controller receives data defining a desired final image from an input channel, and develops time-coordinated signals which energize heads selectively at appropriate times as the medium travels past th…
