Abstract:
A thin film magnetic medium for storing data, said medium comprising:a main recording layer having a first thickness of ferromagnetic material and having a first side and a second side; a first non-ferromagnetic spacer layer located on said first side of said main recording layer; a second non-ferromagnetic spacer layer located on said second side of said main recording layer; a substrate; a non-ferromagnetic underlayer and a first stabilizing layer residing between said substrate and said first non-ferromagnetic spacer layer, wherein said first stabilizing layer has a second thickness of ferromagnetic material which is less than said first thickness; and a second stabilizing layer located on a side of said second non-ferromagnetic spacer layer opposite to said main recording layer, wherein said second stabilizing layer has a third thickness of ferromagnetic material which is less than said first thickness, wherein said first thickness is greater than said second thickness combined with said third thickness.
