Multichannel transducer with glass support elements

Claim 1

A multichannel magnetic transducer assemblage comprising: a unitary I piece which includes a ferrite block member having top, front, bottom and rear faces wherein the intersection between the front and top faces forms a front edge for the top face of the block and the intersection between the top and rear faces forms a rear edge for the top face of the block, a series of uniformily spaced ramp-like slots extending downwardly from a line intermediate said front and rear edges of the top face of said block to a line intermediate the front edge of said block and the bottom face of said block, said series of slots forming a series of teeth along the front edge of said block, a series of spaced C-shaped ferrite slabs bonded to the top face of said block, each of said slabs overlying a respective tooth of said series of teeth to form with said teeth a series of active transducer gaps spaced along the front edge of said block and a corresponding series of back gaps spaced along the rear edge of said block, and a melted glass material filling each of said slots to provide structural support for said teeth and the overlying C-shaped ferrite slabs.
