Latest Patents

Zhiguo Ge's latest patents include innovative designs that enhance the performance of magnetic storage devices. One of his notable inventions is a magnetic element with reduced shield-to-shield spacing. This magnetic stack features a magnetically responsive lamination that includes a ferromagnetic free layer, a synthetic antiferromagnetic (SAF) structure, and a spacer layer positioned between the ferromagnetic free layer and the SAF structure. The design ensures that the magnetically responsive lamination is effectively separated from a sensed data bit stored in an adjacent medium by an air bearing surface (ABS). Additionally, the stack incorporates a first antiferromagnetic (AFM) structure coupled to the SAF structure at a predetermined offset distance from the ABS, along with a second AFM structure separated from the first AFM structure by a first shield layer.

Another significant patent is the sensor stack structure with an RKKY coupling layer between the free layer and the capping layer. This reader stack, designed for magnetic storage devices, includes a top synthetic antiferromagnetic (SAF) layer, a magnetic capping layer adjacent to the top SAF layer, and an RKKY coupling layer positioned between the magnetic capping layer and the free layer. This innovative design allows for effective biasing of the free layer in a reader stack by providing an exchange coupling between the free layer and the top SAF layer.
