Abstract
A plurality of fiber optic cables are bundled into a two dimensional output array which “writes” multiple data tracks onto a recording surface during a single pass of the array. The geometry of the array provides that the data tracks may be spaced at fine intervals when written onto the recording surface without requiring that the fibers of the output array have a correspondingly fine separation. The reduction in the pitch of the written tracks is achieved by staggering multiple rows of equally spaced optical fibers. To build a two dimensional array having relatively equal spacing of fibers, a spacing fixture is used, or, alternatively, the diameter and shape of the fiber cladding itself can be used.
