A seedlayer structure for a high coercivity hard bias layer is disclosed,
having at least one bi-layer seedlayer, including a CrMo layer, and a W
layer fabricated on the CrMo layer. A hard bias layer is fabricated on
the bi-layer seedlayer. Preferably, the seedlayer structure includes two
bi-layer seedlayers, which including a first CrMo layer, a first W layer
fabricated on the first CrMo layer, a second CrMo layer fabricated on the
first W layer, and a second W layer fabricated on the second CrMo layer.
Also disclosed is a high coercivity hard bias stack structure, a magnetic
read head for a disk drive having a high coercivity hard bias stack
structure and a method for fabricating a coercivity hard bias layer for a
magnetic read head.
