PURPOSE:To facilitate the mass production of the titled magnetic head with high reliability, by using an open magnetic type transformer core for a boosting transformer core to improve a step-up type magnetic head and obtaining a magnetic head which has a magnetic core window and fixes a primary coil terminal. CONSTITUTION:A 1-turn step-up type magnetic head is formed by providing a 1-turn winding 2 and a secondary coil 4 between a magnetic head core 1 and a boosting transformer core 3. An open magnetic type transformer core 22 is used in place of the core 3, and a 1-turn winding 23 (primary coil) and a secondary winding 24 (secondary coil) are set as shown by an arrow mark. The 1st and 2nd head cores 21a and 21b are joined together via the glass, and a winding window 25 (magnetic core window) is provided to fix the terminal of the coil 23. Thus a step-up type magnetic head is obtained. |
