METHOD OF MANUFACTURING MAGNETIC RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To form a magnetic recording medium which has a structure separated and made independent with information reaction sections without using micro fabrication techniques and has substantially no ruggedness on the surface. SOLUTION: A diffusion seed layer 2 consisting of a material diffused into a magnetic film by heating is formed on a nonmagnetic substrate 1 and after a magnetic film 3 is formed thereon, the planned separating zone forming regions for separating the information recording sections to be accumulated with the information are locally heated by heating means 4 to splash the material of the diffusion seed layer of the separating zone regions to the magnetic layer and the magnetization of the magnetic film 3 is reduced, by which the information recording sections 5 and the separating zones 6 to separate the information recording sections are formed.
