Abstract
The present invention is directed to provide a magnetic head that is capable of effectively preventing TA noise. A slider 1 is provided with air bearing surfaces 111 and 121. Electromagnetic conversion elements 2 and 3, which are provided toward the trailing edge TR of the slider 1, perform electromagnetic conversion at the air bearing surfaces 111 and 121. The slider 1 is provided with indented portions 114 and projecting portions 115 at the air bearing surfaces 111 and 121 where the electromagnetic conversion elements 2 and 3 are provided. The indented portions 114 are provided in the areas corresponding to the width W2 of the electromagnetic conversion elements 2 and 3 viewed in the direction of the track width further toward the trailing edge TR than the electromagnetic conversion elements 2 and 3. The projecting portions 115 are provided adjacent to the indented portions 114 further projecting out compared to the indented portions 114.
