Microwave assisted magnetic recording (MAMR) was proposed to increase the data storage areal density in hard disk drives [1]. With a localized AC field generated by a spin torque oscillator (STO), MAMR significantly reduces the switching field when t

Return field-induced partial erasure (RFPE) in trailing-edge shielded perpendicular writers has been studied, both by modeling and by experiments. For a given head-media combination, the return field underneath the trailing shield increases with incr

In drive designs with write data rates >1 Gb/s, transitions sent to the write head collide at 1T with reflections from earlier transitions. This increases the need for write-driver voltage headroom, efficient interconnects, and efficient magnetic mat
