Head slider having a terminal group of lubricant of lubrication layer different from that of a medium

An information memory storage device comprising, within a housing having a base, a rotatable medium, a carriage having a head slider at an end thereof, wherein said head slider has a head slider body, and a magnetic circuit which rotates the carriage in opposite directions, said medium including:

• a substrate;
• a magnetic layer on a surface of the medium;
• and
• a lubrication layer on a slider surface of said head slider body,
• wherein a main chain of a lubricant of the lubrication layer of said medium is —(CF2-CF20), —(CF2-0)m;
• and
• a terminal group is selected from a group consisting of Fomblin Zdol family, Fomblin AM 3001 family, Amine family, MORESCO PHOSFANOL family, and Fomblin Tetraol family;
• wherein a main chain of the lubricant of the lubrication layer of said head slider body is —(CF2-CF20)n-(CF2-0)m- the same as the main chain structure of the lubricant of the lubrication layer of said medium;
• a terminal group of the lubricant of the lubrication layer of said head slider body is selected from a group consisting of Fomblin Zdol family, Fomblin AM 3001 family, Amine family, MORESCO PHOSFANOL family, and Fomblin Tetraol family;
• and
• said terminal group of said head slider body is different from the terminal group of the lubricant of the lubricant layer of said medium.
