<P>PROBLEM TO BE SOLVED: To suppress the amount of a lubricant that migrates in a lubricant migration. Ž<P>SOLUTION: A magnetic disk 200 is manufactured that has a body part 210, a bonded layer 222, and a free layer 221. The body part 210 is disk-shaped and stores information. The bonded layer 222 is formed with a lubricant, and is bonded to both-sides surfaces of the body part 210. The free layer 221 is formed of a lubricant that covers the bonded layer 222, with the flowability higher than that of the lubricant that forms the bonded layer 222. The distribution of the bonding ratio in the bonded layer 222 reaches its peak on the way from the outermost circumference to the center. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
