Abstract
By inserting a first antistripping layer comprising a first non-magnetic layerand a first conductive layerbetween a first magnetic layerand a magnetic separation layer, adhesion between the first conductive layerand the magnetic separation layeris improved to prevent the first magnetic layerfrom stripping. In addition, by inserting a second antistripping layer comprising a second non-magnetic layerand a second conductive layerbetween a second magnetic layerand a magnetic gap layer, adhesion between the second conductive layerand the magnetic gap layeris improved to prevent the second magnetic layerfrom stripping.
