Abstract
A method of forming a patterned media includes constraining growth of magnetic grains in a down-track direction without constraining the growth in a radial direction to cause the magnetic grains to align in rows extending in the radial direction. The patterned media may allow for data track radial width to be defined independent of grain size.
