The quantitative difference of the coercivity between the hole and land regions was studied using Kerr microscope. Variation feature of the coercivity over a patterned and non-patterned magneto-optical media surface was acquired by the microscope. The Kerr microscope was equipped with an electromagnet and a charge coupled device camera with 300k pixels resolution. Coercivity difference between the circular hole arrays and land region on patterned surface was clearly identified.
