A magnetic head assembly includes a magnetic head slider with an element-formed surface on which at least one MR read head element is formed, an ABS to be opposed in operation to a magnetic recording medium and a fixing surface that is the other side of the ABS, and a support for supporting the magnetic head slider. The fixing surface of the magnetic head slider is fixed to the support by at least cure-shrinkage resin material layer providing a contractive force when cured. The cure-shrinkage resin material layer has at least one strip-shaped pattern running along a track width direction.
