Abstract
A yoke for supporting a magnetic recording core adjacent a moving recording tape is disclosed. The core has two major surfaces, two side walls, and upper and lower walls. Two wound wire coils are mounted to the core adjacent respective side walls and extend beyond the major surfaces. The yoke includes two opposed major surfaces and a front surface which defines a bearing surface for supporting the recording tape. A narrow slot is formed in the front surface to receive the core. The walls of the narrow slot stabilize the core along the length of the core adjacent the core upper wall. Relief pockets extend between the two major surfaces of the yoke and encompass at least a portion of the narrow slot. The relief pockets permit winding the coils around the core after the core is positioned in the yoke.
