Apparatus comprising magnetically soft underlayer

An apparatus, comprising:

• a magnetically soft underlayer (SUL);
• an interlayer stack overlying the SUL,
• wherein the interlayer stack has a thickness from 56 nm to about 200 nm, and
• wherein the interlayer stack comprises a seed layer of an fcc material;
• and
• a perpendicular magnetic recording layer overlying the interlayer stack,
• wherein a thickness of the SUL in combination with a distance of the SUL from the perpendicular recording layer corresponding to the thickness of the interlayer stack is sufficient to increase a perpendicular component of a magnetic field corresponding to a magnetic transducer head at an angle approaching 45°.
