Abstract

This article describes a method of designing a diskette drive having the head mounted on a swing arm. The path of the head across the diskette is arcuate and not linearly radial with the result that the recorded data on all tracks is not aligned with the read/write head. The problems are described in more detail in U. S. Patent 4,367,505. (Image Omitted) Conventional diskette head assemblies include a read/write head having a gap that preferably is aligned radially with the disk and defines a track of data. To prevent track overlay and cross talk, a guard band is created adjacent each side of a data track by two erase heads that follow on each side of the read/write head gap. At small track radii, i.e., on the inner tracks, the inner erase gap erases a significant portion of the written track.
