A thin film magnetic head is disclosed which includes a magnetoresistive element portion (56) movable over and relative to a magnetic recording medium for reading informations stored therein, upper and lower shielding layers (60,53) disposed to locate the magnetoresistive element portion therebetween for magnetically shielding the magnetoresistive element portion, and upper and lower gap insulative layers (59,55) respectively interposed between the upper shielding layer and the magnetoresistive element portion and between the lower shielding layer and the magnetoresistive element portion. Each of the upper and lower gap insulative layers comprises a hydrogen-incorporated film. The upper gap insulative layer has an increased hydrogen content and a reduced internal stress relative to the lower gap insulative layer. For this, additional stress relaxation layers can also be provided. <IMAGE> |
