ZUSAMMENBAU FUER MONOLITISCHEN MEHRKANAL-MAGNETWANDLER MIT MEHRFACHER AUFSTAPELUNG UND HERSTELLUNGSVERFAHREN.

摘要

A plurality of magnetic blocks is integrally joined side-by-side with a nonmagnetic material therebetween to provide a monolithic block defining parallel transducing gap planes, each pertaining to one multichannel transducer stack. A plurality of first parallel slots in the monolithic block intersects the gap planes to define a plurality of partitions, each partition forming pairs of magnetic pole pieces defining respective transducing gaps pertaining to respective stacks. The transducing gaps of each partition define interlaced transducing channels of the multichannel assembly. Second parallel slots provided along the gap planes have apexes defining transducing gap depths. The resulting transducing channels have uniform gap azimuth and gap depth while uniform internal stack alignment between all the respective stacks is obtained.
