Abstract
Perpendicular recording is expected as high areal density recording system because of strong thermal stability potential and highly efficient writing process. However, large demagnetizing fields in uniformly magnetized areas cause recording demagnetization and signal decrease with time. We propose a new recording design to suppress recording demagnetization for perpendicular magnetic recording, using high nucleation field media. CoPtCrO perpendicular medium with high nucleation field successfully demonstrated the low noise performance. It shows less recording demagnetization and strong thermal stability. CoPtCrO perpendicular medium exhibited good BER performance with ring head recording.
