Abstract: A disk file having on one side of a disk a servo track and a plurality of data tracks all equally spaced on centers and a carriage translatable across the disk and having an array of read/write heads some of which are spaced on centers for the distance equal to the spacing between adjacent ones of said tracks and others of which are spaced on centers for multiples of the distance between adjacent ones of said tracks, the spacing between heads being such that when said heads are successively in alignment with said servo track the others of said heads are aligned with said data tracks.
