SYNCHRONIZATION OF MODIFIED CHUA’S CIRCUITS IN STAR COUPLED NETWORKS

A slider is provided with air bearing surfaces and at the side that faces opposite the medium. Inductive thin film magnetic conversion elements are each provided with pole tips which emerge at the air bearing surfaces. The width of the pole tips in the direction of the tracks, which is perpendicular to the direction of the movement of the medium, is essentially defined by grooves formed at the air bearing surfaces. The grooves gradually become shallower along the direction of the movement of the medium until their bottom surfaces reach the level of the air bearing surfaces.
