Abstract
PURPOSE:To improve dispersibility and output as well as traveling durability by consisting the recording medium of a magnetic layer contg. a binder which is formed by using a hexagonal planar ferromagnetic material having >=9pH and has at least 1X10eq/g anionic polar group. CONSTITUTION:The magnetic recording medium formed by providing a magnetic layer disposed with the ferromagnetic material which is hexagonal planar shape and has an axis of easy magnetization in the direction perpendicular to the flat plate face into the binder on a nonmagnetic base is formed of the magnetic layer contg. the binder which is formed by using the hexagonal planar ferromagnetic material having >=9pH and has at least 1X10eq/g anionic polar group. Conventional thermoplastic resins, thermosetting resins, reaction type resins, and the mixtures composed thereof are used for the binder contg. the anionic polar group. The dispersibility and the output as well as the traveling durability are thereby improved.
