Abstract

The methodology to design a write transducer for recording onto perpendicular media at areal densities beyond 1 Tbit/in was discussed. The single-layer recording media in combination with a ring type head and double-layer recording media with a soft underlayer in combination with a single pole head were compared. The system efficiency was redefined for perpendicular recording to consider the critical role of the soft underlayer. The effects of the using 'soft' magnetic shields around the trailing pole were also elaborated.
