Abstract
A magnetic recording medium including a nonmagnetic base plate with textured trenches formed thereon. The resulting textured nonmagnetic base plate includes a mean line depth Rv of no more than 500 .ANG. and a relative load length tp(90-99) of no more than 120 .ANG.. A method for manufacturing the magnetic recording medium is also disclosed. The resulting magnetic recording medium exhibits substantially fewer micro-scratches and a reduced error frequency, due, in part, to the textured trenches formed on the nonmagnetic base plate.
