Latest Patents

One of his latest patents is titled "Shock Protected High Stack Density Suspension System." This invention features a uniquely configured flexure tongue of a head/gimbal assembly (HGA) that allows for the parallel positioning of a slider air bearing surface (ABS) during merge operations. It also limits the pitch of the slider during non-merge conditions. The design includes a cantilevered end of the flexure tongue with a finger extension for merge operations, while the adjacent portion helps in limiting the pitch of the slider. This innovation ensures that when a merge comb engages multiple flexure fingers in a head stack assembly, the air bearing surfaces of the sliders remain parallel, maximizing disk stack density. The invention also works in conjunction with a prior art roll limiter to normalize the slider at zero pitch during merges.
