Embodiments include electroless deposition of an amorphous nickel-phosphorous coating on a glass, glass-ceramic, ceramic, or aluminum-containing substrate, with an as deposited average surface roughness (Ra) of less than about 16 .ANG., depositing an underlayer, and depositing a magnetic layer to form a magnetic recording medium.
