Abstract
In the manufacture of a transducer head, a plurality of elongated slots are formed in a non-magnetic substrate to receive magnetic cores having a transducing gap. A sealing composition bonds the cores in the slots and the cores are then laser trimmed to predetermined widths and at predetermined core-to-core spacings.
