Abstract:
1. A data storage tape comprising: a substrate; a magnetic layer formed over the substrate, wherein the magnetic layer comprises a perpendicular squareness greater than 50 percent and a longitudinal squareness less than 50 percent; a servo track on the magnetic layer; a servo pattern in the servo track, wherein the servo pattern comprises a plurality of servo marks each comprising a pattern remanence magnetization in a first directional octant that borders a perpendicular plane perpendicular to both the substrate and a length of the substrate and is disposed on a first side of a longitudinal plane parallel to the substrate; and a non-pattern area in the servo track, wherein the non-pattern area has a non-pattern remanence magnetization in a second directional octant bordering the perpendicular plane and disposed on a second side of the longitudinal plane opposite the first side.
