Abstract
According to one embodiment, a magnetic recording head records information in a magnetic recording medium by shingled magnetic recording. The magnetic recording head includes a magnetic pole and a shield opposing the magnetic pole. The magnetic pole has a shield-opposing surface opposing the shield. The shield-opposing surface includes a first portion and a second portion. A position of the second portion in a track width direction is different from a position of the first portion in the track width direction, the track width direction intersecting a first direction from the magnetic pole toward the shield. The first portion records the information in the magnetic recording medium after the second portion in the shingled magnetic recording. A first distance between the first portion and the shield is shorter than a second distance between the second portion and the shield. The shield-opposing surface is tilted with respect to the first direction.
