Abstract: PROBLEM TO BE SOLVED: To prevent the contamination of a head and decrease in output caused by repeated use by forming a ground layer on a magnetic layer formed on a supporting body in such a manner that the thickness of the ground layer is continuously changed and the max. thickness and the recording wavelength are in a relation satisfying a specified formula. SOLUTION: A magnetic coating material essentially comprising iron is applied and dried on a supporting body 3 such as a PET film to form a magnetic layer 2, on which a ground layer 3 containing carbon or silicon in which the thickness is continuously changed is formed. The period L between the peaks in this wave form is specified to 0.5-50m, and the max. thickness d (μm) is determined to satisfy the relation of 54.6×d/λ<=2, wherein λ is the recording wavelength (μm). For example, the layer 3 is formed to have 150Å max. thickness and 30Å min. thickness and 15m period L by using Si as a target in vacuum while introducing oxygen gas, thereby preventing the deposition of contaminant on a reproducing head and preventing decrease in the output or increase in dropout even when the head is repeatedly used.
