Abstract
A multielement magnetic head is formed with a closure section having a nonmagnetic ceramic substrate on which a thin layer of magnetic ferrite is deposited and processed. The thin ferrite layer is cut to define the separate transducing elements and data track separation. The closure section is joined to a wafer formed from a ferrite substrate and a thin film conductive coil means.
