Filed: 1999-04-16
Abstract: PROBLEM TO BE SOLVED: To prevent deformation on the ABS(air bearing surface) side of magnetic head due to temperature rise by disposing a 1st lower protective layer on the ABS side and a 2nd lower protective layer having a lower Young's modulus than the 1st protective layer next to the 1st protective layer and under at least part of a coil. SOLUTION: The magnetic head 20 has a lower protective layer 2a consisting of Al2O3 on the ABS side on a substrate 1, a lower protective layer 2b consisting of a photoresist such as novolak resin, having a lower Young's modulus than the lower protective layer 2a and disposed next to the lower protective layer 2a and under at least part of a coil 6 to the opposite side of the ABS, a lower magnetic layer 3 and an upper protective layer 9.
