Magnetic recording medium

摘要

A magnetic recording medium with improved output characteristics and durability is provided by using magnetic powder comprising iron-containing particles each of which carries a compound containing aluminum and/or a compound containing silicon in such amounts that, in the whole magnetic powder, a weight ratio of silicon to iron is from 0.010:1 to 0.150:1, a weight ratio of aluminum to iron is from 0.040:1 to 0.150:1, and a weight ratio of aluminum to silicon is from 1:1 to 15:1.
