Abstract
The intrinsic dynamic response of a perpendicular system with the underlayer was analyzed and compared with the intrinsic dynamic response of a longitudinal system. Three-dimensional finite element modeling and inductance measurements were used to design an ultra-high frequency perpendicular system. The magnetic flux dynamics of the recording system with a soft underlayer were studied using Kerr imaging microscopy. An optimally designed perpendicular system does not show fundamentally degraded dynamic performance compared to an equivalent longitudinal system.
