Abstract
A vertical recording head structure combines a tri-pad shaped slider body with a uniquely shaped thin-film recording element disposed along a trailing edge of the slider body. The recording element, or transducer, includes a narrow probe tip for writing data to a rotating magnetic disk. The recording element also includes a wide permalloy area to distribute the magnetic field returning from the disk. The wide area spreads the magnetic field lines such that the returning flux is kept from unintentional writing or reading information. The size and orientation of the air-bearing surfaces on the tri-pad slider body causes the slider to assume a flying attitude wherein the leading edge is lifted above the rotating magnetic disk, and the trailing edge is in substantial contact with the disk, during data transfer operations.
