Abstract
The present invention relates to a thin-film magnetic head with a heater. A thin-film magnetic head includes a substrate, a magnetic read head element that has a shield area and is formed on the substrate, a magnetic write head element that has a pole area and is formed on the opposite side of the substrate with respect to the magnetic read head element, an overcoat layer that covers the magnetic read head element and the magnetic write head element and is formed on the substrate, a heater that heats at least during the magnetic read head element or the magnetic write head element in operation and is formed in the overcoat layer, and a slit area that splits the shield area in a shield length direction and is made of lower thermal conductivity material than the one of the shield area.
