Examples of a magnetic recording head slider, a head gimbal assembly and methods of manufacturing each are disclosed. A permanent connection between an aluminum oxide sapphire and an aluminum oxide ceramic is attained by a first connecting later comprised of a manganese-silicate glass, in which at least one of the metals molybdenum, tungsten, palladium or platinum is incorporated, and by a second connecting layer comprised of a manganese-silicate glass. The nitrogen-containing compound having a resonance structure when protonated is capable of assuming a chemical structure in which the multiple bond represented by the double bond is moved, with the atoms constituting the molecule not changing their positions. For example, mechanisms create new instances of previously shared objects so that legacy applications can continue to expect exclusive access to those objects.
