ABSTRACT:
In lubricant (5) of a magnetic recording medium made of conventional perfluoropolyether, one or more conductive high molecular compound is mixed. The conductive lubricant (5) prevents electric charge generated by frictional electricity from staying on the medium surface, and effectively prolongs the head-life by suppressing the break of the head element because of electric discharge between the disk medium and the head element. By employing the conductive lubricant, magnetic recording media and magnetic recording devices which are more reliable and durable can be realized.
