<p><P>PROBLEM TO BE SOLVED: To form a transition line of good linearity while generating high magnetic field strength, and to prevent recorded information on an adjacent track from being deteriorated due to skew. <P>SOLUTION: A perpendicular magnetic recording head is constituted so that film thickness in the down track direction of a main magnetic pole increases as it goes away from an air bearing surface, and a central position of a part (air-bearing-surface part) exposed to the air bearing surface of the main magnetic pole in the film thickness direction may be located in a trailing side with respect to the central position of the part having the largest film thickness in the part (set-back part) which is set back from the air bearing surface in the direction of film thickness. The film thickness in the down track direction of the air bearing surface part is preferably not larger than half the film thickness of the set-back part. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
