ABSTRACT:
An integrated magnetic head unit includes a housing and a substrate provided in the housing. The substrate supports a plurality of electromagnetic transducing elements including respective transmission elements which are connected to bonding pads on the substrate. A silicon plate covers the transducing elements and is arranged in a good thermally-conducting relationship with the transducing elements and with the housing. The cover plate is arranged such that the bonding pads are exposed.
