Abstract
Provided is a vertical writing type magnetic head including a substrate, a bottom pole formed on the substrate, and a top pole aligned with and spaced a predetermined distance apart from the bottom pole, wherein the bottom pole has a narrower width than the top pole. The magnetic write head is constructed such that the width of a bottom pole is narrower than that of a top pole, thereby reducing extension of a magnetic field at sides of a top pole and effectively preventing erasure of information of an adjacent track due to the bottom pole overlapping the adjacent track when there is a constructional skew in a hard disk drive.
