ABSTRACT:
Magnetic head structure is operated to record both servo magnetic transitions, and data magnetic transitions, in magnetic media, the servo transitions buried relative to the data transitions, the servo transitions recorded along bands and the data transitions recorded along side-by-side tracks, the bands being wider than the data tracks, the data transitions having lateral lengths greater than track width. The magnetic head structure typically employs multiple magnetic flux servo write gaps, including a leading first gap extending at one angle .alpha. and a trailing second gap extending at an angle .beta., relative to the direction of travel of the media past the head structure, the first and second flux gaps spaced and positioned to span multiple of the data tracks.
