1360448 Mounting magnetic transducers INTERNATIONAL BUSINESS MACHINES CORP 6 Dec 1971 [28 Dec 1970] 56459/71 Heading G5R A thin film magnetic transducer 20 is mounted on one face 15 of a support block 18 of insulating material which has internal electrical conductors 11 connecting the transducer 20 to an upper face 14 of the block 10, on which is mounted an integrated circuit chip 30. The block 10 is formed by firing together a stack of layers of ceramic material. Internal passages 12, 13 are formed both parallel and normal to the original layers and are filled with molten metal to form the conductors 11. The faces of the block 10 may be lapped or polished to expose the ends 18 of the conductors 11, electrical connection being made to the conductors 11 by globules of solder 40. The transducer 20 is formed by deposition of successive conducting and magnetic films on a non-magnetic plate substrate. As shown each transducer 20 has a single turn winding 23 and a gap 21, and is mounted with the substrate outermost. A plurality of transducers 20 with respective chips 30 may be mounted on a common block 10 to form a flying head assembly. |
