Abstract
A magnetic head apparatus including a magnetic head slider having at least one thin film magnetic head element, a suspension mounting the magnetic head slider on one face thereof, an IC chip mounted with a circuit for the thin film magnetic head element and a support arm fixedly supporting the suspension in which the IC chip is mounted on the one face of the suspension and is thermally coupled to the support arm.
Claims9
A magnetic head apparatus comprising:
- a magnetic head slider having at least one thin film magnetic head element;
- a suspension mounting the magnetic head slider on one face of the suspension;
- an IC chip mounted with a circuit to drive the thin film magnetic head element;
- and
- a support arm configured to rigidly support a first section of the suspension such that a second section of the suspension extends beyond the support arm,
- wherein the IC chip is mounted on the one face of the suspension in a substantially co-planar orientation with the support arm and is thermally coupled to the support arm.
A magnetic disk apparatus comprising a magnetic head apparatus, the magnetic head apparatus including:
- a magnetic head slider having at least one thin film magnetic head element;
- a suspension mounting the magnetic head slider on one face of the suspension;
- an IC chip mounted with a circuit to drive the thin film magnetic head element;
- and
- a support arm configured to rigidly support a first section of the suspension such that a second section of the suspension extends beyond the support arm,
- wherein the IC chip is mounted on the one face of the suspension in a substantially co-planar orientation with the support arm and is thermally coupled to the support arm.
