摘要：
A magnetic disk has a magnetic medium or a protection film, and a solid lubrication film formed on the medium or the protection film and consisting of a fullerene C60, C 70 or C84 and an alkyl or allyl-chained fullerene. The lubrication film provides the disk with high mechanical durability and high linear recording density.
