Magnetic recording medium comprising ferromagnetic particles and a compound with a pyrimidine or tetrazaindene structure

摘要

A magnetic recording medium is disclosed which includes a magnetic layer containing ferromagnetic metal particles containing Al in an amount of 0.5 to 6% by weight per the total weight of metal components contained in the ferromagnetic metal particles, the ferromagnetic metal particles having the surfaces thereof coated with a compound or compounds of formula (1) or (2), as described herein. The magnetic recording medium has reduced abrasion with respect to magnetic heads and does not cause magnetic head fouling even under low humidity conditions.
