Popis:	This paper addresses the effect of a shield for the ring head to improve high track density. We analyzed the shape and the position of the shield with the finite-element method and checked the effect of the shield using a three-dimensional magnetic recording simulator in which a curing magnetic reversal model and self-consistent magnetic calculations were combined with the finite-element method. In this analysis, all components of the fringing field of the shield head were reduced, especially for the 30-degree components, which refers to the orientation angle of obliquely oriented metal evaporated tapes. We calculated the side erase band (SEB) from recorded magnetization on DC erased obliquely oriented metal evaporated tapes and found an optimal shield shape and position with respect to the head/media spacing. The well designed shield head was advantageous in having an SEB that was less than half that of a conventional head, was effective for achieving high track density in a tape storage system.
