    • A method for manufacturing a magnetic head is provided to control a lead core and a lead gap finely and accurately and to obtain an element shape stably. A method for manufacturing a magnetic head includes a step of forming a magnetic resistance effect film(16) whose upper surface is formed with a first grinding-durable film having grinding selection capability for a magnetic material, on a first region of a lower electrode(12), a step of forming a magnetic domain control film(24) at a whole surface on the lower electrode with the first region, a step of removing the magnetic domain control film on the magnetic resistance effect film by the first grinding-durable film as a stopper and remaining the magnetic domain control film selectively on a second region closed to the first region, a step of removing the first grinding-durable film, and a step of forming an upper electrode(34) on the magnetic resistance effect film without the first grinding-durable film.
    • 提供一种用于制造磁头的方法,以精细且精确地控制引线芯和引线间隙,并且稳定地获得元件形状。 一种制造磁头的方法包括在下电极的第一区域形成上表面形成有具有用于磁性材料的研磨选择能力的第一耐磨薄膜的磁阻效应膜(16)的步骤( 12),在具有第一区域的下电极的整个表面上形成磁畴控制膜(24)的步骤,通过第一耐磨膜除去磁阻效果膜上的磁畴控制膜的步骤 作为止动器,并且在与第一区域相邻的第二区域上选择性地保留磁畴控制膜,去除第一耐磨损膜的步骤,以及在磁阻效应膜上形成上电极(34)的步骤,没有 第一耐磨薄膜。
