专利汇可以提供Magnetic head device and magnetic head专利检索,专利查询,专利分析的服务。并且PURPOSE: To increase a pitch angle and to improve traceability by providing a recessed groove on the air inflow terminal side of a magnetic head on a plane opposite to the air bearing plane of a slider in a direction to cross with the running direction of the air, and setting a load point at a side nearer to an air outflow terminal side than the intermediate part of length of the magnetic head observing in the running direction of the air.
CONSTITUTION: Since the load point P
2 is set at the side nearer to the air outflow terminal side than the intermediate part P
3 of the length in the running direction (a) of the air, the area of the air bearing plane 101 at an air inflow side becomes larger than that of the air bearing plane 101 at the air outflow terminal side setting the load point P
2 as reference, and dynamical pressure generated at the air inflow side becomes larger than that generated at an air outflow side. Also, since the magnetic head is provided with the recessed groove 104 formed at the air inflow side of the plane at the side opposite to the air bearing plane 101 in the direction crossing with the running direction of the air, the difference of mass between the air inflow terminal side and the air outflow terminal side setting the load point P
2 as reference can be reduced, which reduces a moment of inertia. Thereby, the pitch angle can be increased and the traceability can be improved.
