ABSTRACT:
Provided is a thin-film magnetic head, in which the magnetic spacing can be controlled appropriately, regardless of the presence of the variation in height of the medium-opposed surface of the closure. The thin-film magnetic head includes: at least one head element formed on or above an element-formation surface of a substrate, for reading data from a magnetic recording medium and/or writing data to a magnetic recording medium; an overcoat layer formed on the element-formation surface so as to cover the at least one head element; and at least one closure adhered to at least a portion of an upper surface of the overcoat layer. Here, at least one of the at least one closure includes at least one element for adjusting the height of a medium-opposed surface of the closure. The element is preferably a heating element provided within the closure.
