Magnetic data recording system with mirror image asymmetric magnetic write elements

摘要

A magnetic disk drive system configured for shingled magnetic data recording wherein data tracks are recorded in an overlapping fashion on a magnetic media. The disk drive system includes magnetic write heads that are asymmetric so as to have increased writing at one side of the write head. The magnetic disk drive system includes magnetic write heads that are mirror images of one another so that write heads located at opposite surfaces of the magnetic media (e.g. one head facing up and one facing down) end up having preferential writing in the location relative to inner and outer diameters of the magnetic media.

1. A magnetic disk drive, comprising:
a magnetic media having first and second opposite surfaces; a first slider arranged adjacent to the first surface of the magnetic media having a first magnetic write head formed thereon; and a second slider arranged adjacent to the second surface of the magnetic media and having a second magnetic write head formed thereon; wherein the first and second magnetic write heads each have a magnetic write pole and are each configured to produce a magnetic write field that is laterally asymmetrical relative to the magnetic write pole and are mirror images of one another.
