PERPENDICULAR MAGNETIC RECORDING MAGNETIC HEAD WITH MAIN MAGNETIC POLE AND SHIELD

摘要

PROBLEM TO BE SOLVED: To prevent the occurrence of adjacent track erasure caused by a seed layer contained in a magnetic structure.SOLUTION: A magnetic head includes a magnetic structure. The magnetic structure is configured to include a first shield 16A, a magnetic layer 42 laminated on the first shield 16A, and a seed layer 87. The first shield 16A has a front end face disposed on a medium opposite surface 80 and a top surface 16Ab. The magnetic layer 42 has a front end face disposed on the medium opposite surface 80 and an undersurface 42c. The top surface 16Ab of the first shield 16A includes a first region 16Ab1 including an end located on the medium opposite surface 80 and a second region 16Ab2 which is located farther from the medium opposite surface 80 than the first region 16Ab1. The seed layer 87 does not exist on the first region 16Ab1 of the top surface 16Ab of the first shield 16A, but exists on the second region 16Ab2.
