As a magnetic recording disk rotates at an elevated temperature, lubricants necessary for functional operation of this disk can spinoff to a point where mechanical durability is a concern. The spinoff tendency is lessened significantly by adding functional groups (like acids or alcohols) to the ends of the molecules used as the lubricant. These new structures attach to the disk under certain time and temperature conditions.
