ABSTRACT:
A novel magtnetoresistive head unit includes an upper shield film and a lower shield film electrically connected to electrodes connected with an external source which are shorted by a shorting circuit without the intermediary of an MR element. The current due to static electricity generated in the process of element formation is made to flow through the shorting circuit thereby to prevent the electrostatic breakdown of the MR element and the dielectric breakdown between the MR element and the shield films. After cutting out a slider from the substrate, the upper and lower shield films are shorted by the shorting circuit, thereby preventing the electrostatic breakdown of the magnetoresistive element and the dielectric breakdown between the magnetoresistive element and the shield films during the assembly and transportation. The electrostatic breakdown is also prevented in the processes from the formation of the magnetoresistive (MR) element to the mounting of the MR element on the apparatus, thereby making it possible to fabricate an MR head and a write-read separated magnetic head with a high yield.
