Magnetic head core arrangement having medium facing surface sides formed of single-crystal ferrite

A magnetic core arrangement for a magnetic head, comprising:

• a pair of magnetic cores abutting together and defining a magnetic gap therebetween;
• said magnetic cores each comprising a lower magnetic core portion formed of poly-crystal ferrite and a layer on top of each of the magnetic core portions formed of single-crystal ferrite, and wherein the magnetic gap is formed between the layers of single-crystal ferrite;
• and
• a medium facing top surface of the single-crystal ferrite layers being a {100} plane and vertical abutment surfaces of the layers at which said magnetic gap is formed being another {100} plane of the single-crystal ferrite layers.
