Abstract:
A method for manufacturing a thin film recording head, comprising:forming a first hard-cured photoresist layer over a lower magnetic substance;forming a metal underlying layer for plating over said first hard-cured photoresist layer;forming a coil layer on said metal underlying layer, said coil layer being configured in a coil pattern;removing unnecessary portions of said metal underlying layer to expose a top surface of said first hard-cured photoresist layer by ion-milling in Ar atmosphere with an acceleration voltage of ion-milling being equal to or less than 500 V thereby maintaining a hydrophilic content of said first hard-cured photoresist layer at a predetermined level or less;forming a second hard-cured photoresist layer over said coil pattern: andforming an upper magnetic substance on said second hard-cured photoresist layer.
