MAGNETIC HEAD AND MAGNETIC DISK UNIT MOUNTING THE SAME

摘要

PROBLEM TO BE SOLVED: To improve the curve of a magnetization flipping shape of a recording bit cell by making the magnetic field distribution of a recording head linear. SOLUTION: A single magnetic pole head having a main magnetic pole 1 and an auxiliary magnetic pole 3 is arranged with a magnetic material 32 on a trailing side of the main magnetic pole and the magnetic material is provided with a projecting part 32a projecting toward the main magnetic pole. The width Nw on the side facing the main magnetic pole of the projecting part is made smaller than the width Tww on the trailing side of the main magnetic pole. COPYRIGHT: (C)2005,JPO&NCIPI
