包含铁磁颗粒和具有嘧啶或四氮茚结构的化合物的磁记录介质

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.
摘要（中）：

公开了一种磁记录介质，其包括含铁磁金属颗粒的磁性层，所述铁磁金属颗粒含有铁含量为铁磁性金属颗粒中所含金属组分总重量的0.5至6重量％的Al，其表面涂覆有强磁性金属颗粒 与式（1）或（2）的化合物或化合物反应。 磁记录介质相对于磁头具有减少的磨损，即使在低湿度条件下也不会引起磁头结垢。
