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 reading side, the downstream side with respect to the rotating direction being the trailing 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.
A magnetic head comprising a magnetic head slider including a slider main body which flies with a medium opposing surface being directed to a rotated magnetic recording medium and which is provided with a magnetic core for performing recording or reproduction of magnetic information, wherein there is provided on the medium opposing surface of the slider main body a rail portion 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 reading side, the downstream side with respect to the rotating direction being the trailing 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 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.
A magnetic head comprising a magnetic head slider including a slider main body which flies with a medium opposing surface being directed to the rotated magnetic recording medium and which is provided with a magnetic core for performing recording or reproduction of magnetic information, wherein, in the slider main body, the upstream side with respect to the rotating direction of the magnetic recording medium is the reading side, the downstream side with respect to the rotating direction being the trailing side. wherein a rail portion for flying the slider main body is formed on the medium opposing surface of the slider main body so as to extend from the reading side to the trailing side, and wherein there is provided in the end portion on the trailing side of the rail portion a rail step portion which is positioned in a corner portion of the medium opposing surface on the trailing side of the slier main body and which is lower than the other portion of the rail portion.
