Abstract
A magnetic servo write head incorporates timing pattern read and write heads that are non-symmetrically slanted relative to an adjacent servo write head to improve timing pattern detection for a timing pattern written at an edge of a magnetic storage media. The slanted orientation of the timing write and read heads provides optimized timing pattern location and track width on a magnetic tape, while also allowing a sufficient number of windings to be used on an associated coil to improve overall signal-to-noise ratio.
