摘要
A magnetic head for perpendicular recording on double layer media with suppressed side writing and controlled write width is disclosed. The present invention reduces the problem of side writing and controls the write width of the writing element by providing a writing element with a trailing edge sized dimensionally larger than the leading edge, side shields, and specifically spaced writing gaps placed at various distances between the write element and the side shields, return poles, and the main pole.
