The recorded magnetization structures of longitudinal and perpendicular recording media were investigated by magnetic force microscopy in a temperature range between −50 and 300 °C. We found that when the sample temperatures are increased, variations in recorded magnetization occur preferentially in regions recorded with shorter bit lengths for longitudinal media. On the contrary, they tend to occur in regions recorded with longer bit lengths for perpendicular media. The behaviors of variations in magnetization structures with heating differ slightly bit by bit even for similar bit lengths.
