Abstract
PURPOSE:To improve dispersibility and output as well as traveling durability by consisting the titled medium of a magnetic layer having a binder for which a hexagonal planar ferromagnetic material having <=5pH is used and which has at least 1X10<-5>eq/g cationic polar group. CONSTITUTION:The magnetic recording medium formed by providing the magnetic layer dispersed with the ferromagnetic material which is hexagonal planar and has the axis of easy magnetization in the direction perpendicular to the plane surface into the binder is constituted of the magnetic layer having the binder for which the hexagonal planar ferromagnetic material having <=5pH is used and which has at least 1X10<-5>eq/g cationic polar group. There are respective Co substitution products of barium ferrite and strontium ferrite as the more particularly preferable ferromagnetic material which is hexagonal planar and has the axis of easy magnetization in the direction perpendicular to the plane surface. Conventional thermoplastic resins, thermosetting resins, reaction type resins and the mixture composed thereof are used as the binder contg. the cationic polar group. The magnetic recording medium which is improved in the output and the traveling durability is thereby obtd.
