ABSTRACT:
This disclosure is directed to an amorphous magnetic head which includes a main core having core halves each formed from non-laminated thin sheets of amorphous magnetic material, a non-magnetic spacer, with the core halves being abutted against each other through the non-magnetic spacer disposed in a front gap which is provided between the core halves and whose lower edge is defined by a coil winding opening formed in the core halves, and a set of reinforcing members applied onto opposite sides of the main core to hold the core halves between them. Resinous material is infiltered between the respective reinforcing members and the core halves for integration of the respective elements into one unit. The disclosure also relates to a method of manufacturing such an amorphous magnetic head on a large scale in an efficient manner.
