摘要:
Disclosed is a magnetic head in which there is no fear of the surface of the magnetic recording medium being damaged by the acute edge portion of the magnetic head if the magnetic head approaches the magnetic recording medium in an inclined state. According to the present invention, there are provided on the medium opposing surface of the slider main body rail portions for causing the slider main body to fly, wherein, in the slider main body, the upstream side with respect to the rotating direction of the magnetic recording medium is the leading side, the downstream side with respect to the rotating direction being the trailing K side, and wherein there is provided in a corner portion of the medium opposing surface on the trailing side of the slider main body a protrusion which is lower than the sub rail portion and which is closer to the magnetic recording medium than the end portion on the trailing side of the slider main body in the rolling state of the slider main body.
