Abstract
By inserting a first antistripping layer comprising a first non-magnetic layer and a first conductive layer between a first magnetic layer and a magnetic separation layer adhesion between the first conductive layer and the magnetic separation layer is improved to prevent the first magnetic layer from stripping. In addition, by inserting a second antistripping layer comprising a second non-magnetic layer and a second conductive layer between a second magnetic layer and a magnetic gap layer adhesion between the second conductive layer and the magnetic gap layer is improved to prevent the second magnetic layer from stripping.
