Write head designed for adjusting relative write phase between subtracks of a patterned media hypertrack

摘要

A magnetic recording system configured for recording to a bit patterned media using both hypertrack recording and shingled recording. The magnetic recording system includes a write pole with a notched trailing edge that results in a write bubble with a trailing edge that has two outer convex lobes separated by a centrally disposed concave region. By locating one of the lobes over first and second data tracks of a hypertrack, a proper alignment of the relative phase of the two tracks can be maintained. Further adjustment to the alignment can be achieved by adjusting the radial location of the write head.

1. A system for magnetic data recording, comprising:
a magnetic media; and a magnetic write head having a magnetic write pole, the magnetic write pole being configured to produce a magnetic write bubble on the magnetic media, the write bubble having first and second convex lobes; wherein the write pole is configured with a trailing edge having a centrally disposed notch; and a trailing magnetic shield having a centrally disposed tab that extends toward the centrally disposed notch of the trailing edge of the write pole.
