Abstract
An inductive vertical or horizontal read/write head element for use in rigid magnetic disk files. The element is comprised of at least three spaced apart poles, each of said poles having a flux path extending from said head means, magnetically connecting said path, and at least two electrical coils positioned about said flux paths for inducing a flux in said flux paths. The element also has tracking capabilities when the first and last poles are offset from the other poles, which are essentially aligned.
