Latest Patents
One of Pham's latest patents is a magnetic write head designed for improved manufacturability, featuring a larger write field and reduced adjacent track erasure. This innovative write head includes a pedestal throat height that defines a bottom pole, which is substantially recessed from the air bearing surface. Additionally, it incorporates a top pole that defines a nose closer to the air bearing surface than the pedestal zero throat. This design achieves a high ratio of off-track to on-track field, significantly mitigating the erasure problem of adjacent tracks caused by magnetic flux saturation, with a potential ratio of 1:4.
Another significant patent involves a head stack assembly that includes a trace suspension assembly backing layer and a ground trace for grounding a slider. This assembly features a flex cable assembly, an actuator arm, and a load beam coupled to the actuator arm. The design includes a dielectric layer on the backing layer and a ground trace that extends along the actuator arm, ensuring electrical connection to the slider and flex cable assembly for effective grounding.
