Magnetic recording head and method for manufacturing |
摘要 |
A method is disclosed which manufactures a recording head adapted to be moved relative to a recording medium, which is comprised of a conductive substrate and dielectric layer formed on the conductive substrate, to permit data to be recorded on the recording medium with the use of a conductive/magnetic toner on the recording medium. A conductive/magnetic sheet is attached to an insulating substrate of a first size with an adhesive layer therebetween, the first size of the insulating substrate is greater than a second size thereof defined by an insulating substrate of a finally completed recording head. The conductive/magnetic sheet is selectively etched to form an array of slits at a predetermined interval with both ends of the slits located beyond the side edges of an insulating substrate of a finally completed recording head. At one side edge portion of the conductive/magnetic sheet the conductive/magnetic sheet is electroplated to form a plated layer for a bonding pad. Those areas of the conductive/magnetic sheet, plated layer and insulating substrate, which are located beyond the side edge of the insulating substrate of the finally completed recording head, are cut to form a parallel array of electrodes and a bonding pad on one side edge portion of the conductive/magnetic electrodes.
