Abstract
Data representations are translated on a rotating disc utilizing multiple transducers at different radial positions. The disc is logically formatted into selected concentric bands. Within each band data representations are translated alternately in a repetitive sequence among a selected number of transducers characteristic of the particular band. By appropriately selecting band format parameters and increasing the characteristic number of transducers as a function of decreasing band radial position the track data density may be maintained within selected limits.
