Abstract
In high-speed high-density recording, heat generation becomes a problem as high-frequency modulation and a strong magnetic field of a magnetic head are realized. A transducer supporting structure is provided including a thermally coupling contact portion extended from a part of a suspension and brought into contact with a magnetic core. Heat generated in a coil is dissipated to the suspension via the magnetic core and the thermally coupling contact portion.
Claims2
A transducer-supporting structure comprising:
- a transducer for recording and reproducing information to and from a medium;
- a transducer mounting section mounted with said transducer and configured to contact said medium by means of mechanical action or to maintain a fixed distance from said medium;
- a suspension which supports said transducer mounting section and elastically positions said transducer in a direction so as to move said transducer to and from said medium;
- and
- a thermal coupling member extending between said transducer and said suspension for thermally coupling said transducer with said suspension,
- wherein said thermal coupling member is a gel-form substance, said transducer and said suspension being coupled thermally with each other via said gel-form substance,
- at least a part of heat generated in said transducer is dissipated through said suspension via said gel-form substance, and
- said transducer is an electromagnetic transducer.
