A tape head readwrite module that has a composite air bearing surface, and a method and apparatus for embedding a chip in a substrate to form a composite air bearing surface. A preferred blend contains from about 5% to about 20% by weight of the europium-activated alkaline earth phosphor. The diffuse reflection layer has a diffuse reflectance of greater than or equal to 75% and less than 100%. Conductive material is formed therewithin. The electronic system is also provided with a devise that is capable of distributing power to the electronic component and simultaneously removing heat away from the electronic component.
