1. A data storage device, comprising:
a magnetic recording head assembly, configured to read from and write to a magnetic media, comprising:
one or more rows of chiplets, each of the one or more rows of chiplets having a leading edge, a trailing edge, a first side edge, and a second side edge, the first and second side edges being disposed between the leading edge and the trailing edge; and
one or more sensor guards disposed adjacent to at least one of the first side edge and the second side edge of each of the one or more of rows of chiplets, wherein each of the one or more sensor guards comprises:
a first surface disposed at a media facing surface (MFS);
a second surface disposed perpendicular to the first surface;
a third surface disposed perpendicular to the first surface and parallel to the second surface, wherein the third surface is coupled to the first surface; and
a fourth surface disposed perpendicular to the second surface and parallel to the first surface, wherein the fourth surface is coupled to the second surface and the third surface, and wherein the first, second, third, and fourth surfaces form a continuous step-like shape.
