Abstract :
The structural, magnetic, and recording properties of longitudinal recording media with CrMoB underlayer were studied and compared to those with CrMo underlayer. Media with CrMoB underlayer have smaller grain size, better grain segregation, lower coercivity, and better recording performance than media with CrMo underlayer.
