Magnetic head having arrays of tunnel valve read transducers

摘要: An apparatus, according to one embodiment, includes: a module, and plurality of tunnel valve read transducers arranged in an array extending along the module. Each sensor structure, upper magnetic shield, lower conducting spacer layer between structure electrically insulating layers on opposite sides structure. The includes cap layer, free barrier reference antiferromagnetic layer. Moreover, height measured direction perpendicular media bearing surface module is less than width cross-track intended travel.
