Abstract
The narrow-track perpendicular magnetic heads with multilayered CoZrCr/Ti main-pole films developed here reproduce output signals having increased stability as the number of pairs of CoZrCr layers increases. To see why, a Kerr-effect apparatus was used to measure the relationship between dynamic domain behavior and the number of pairs of CoZrCr layers for multilayered narrow CoZrCr/Ti stripes of different widths. Increasing the number of pairs of CoZrCr layers suppressed wall displacement and stabilized the domain structure. The domain stability agreed fairly well with the stability in perpendicular heads having multilayered CoZrCr/Ti main-pole films.Keywords
