Method for manufacturing a thin film magnetic head |
摘要 |
The invention is a method of manufacturing thin film magnetic heads usable for magnetic recording and reproducing drive devices such as magnetic disk drive devices. The method is characterized by forming a first magnetic film in a primary pattern which is larger than its definitive pattern and of which its edges are located within frames which are used in a frame-plating method for a second magnetic film. The second magnetic film is then formed by the frame-plating method and the first magnetic film is etched into its definitive pattern by using the second magnetic film as a mask.
