Abstract
Write windings are deposited on a ferrite half yoke mounted on a titanium body, and magnetoresistive elements are deposited on another ferrite half yoke mounted on another titanium body. A center section comprising a sandwich of silver-copper shielding material between two ferrite sheets has glass-filled slots cut on one side thereof. The center shield is placed between the write and read sides with the write windings placed between pairs of glass-filled slots and with the magnetoresistive elements in contact with the opposite surface of the center shield. The write windings and the magnetoresistive elements are connected to connector blocks prior to final assembly, and the write and read sides and the center section are pressured together by bolts through two end pieces, forming a vise-like structure.
