Patent ID: 7038892

Claim:
A magnetic storage system, comprising: a moveable magnetic recording medium; an actuator disposed proximate to the moveable magnetic recording medium; and a read head, coupled to the actuator, for reading data on the moveable magnetic recording medium, the read head comprising a spin valve structure including: a ferromagnetic free layer structure that has a magnetic moment; a ferromagnetic pinned layer structure having a magnetic moment; a nonmagnetic conductive spacer layer between the free layer structure and the pinned layer structure; and an anti-ferromagnetic pinning layer coupled to the pinned layer structure for pinning the magnetic moment of the pinned layer structure; hard magnetic thin films disposed on both sides of the free layer structure; and a hard bias seedlayer structure adjacent to at least a portion of the spin valve structure, wherein the hard bias seedlayer structure comprises at least a layer consisting of silicon and a layer comprising chromium or chromium molybdenum.
