Abstract:
A read/write head comprising:a slider substrate; a read shield including a bottom magnetic shield layer on the slider substrate and a shared magnetic shield layer that is spaced apart from the bottom magnetic shield layer; a write head disposed on the shared magnetic shield layer; a read sensor disposed between the bottom magnetic shield layer and the shared magnetic shield layer, the read sensor being spaced apart from the read shield by reader magnetic gaps; electrically insulating layers on the read sensor, the electrically insulating layers forming thermal resistance between the read sensor and the read shield; a thermally conducting nonmagnetic metal layer comprising a metal selected from the group of tungsten and chromium, the metal layer being deposited on the read shield in a first one of the reader magnetic gaps, the thermally conducting nonmagnetic layer reducing the thermal resistance without a corresponding reduction in the reader magnetic gaps; and a seed layer bonding the metal layer to the read shield, wherein the seed layer is a mixture of metals including metal matching metal used in the read shield and metal matching metal used in the metal layer.
