Latest Patents
Josef Walian holds a patent for an "Advanced PZT glide head design and implementation for a small slider." This invention features an enhanced piezoelectric sensor that detects a predetermined bending mode frequency in the vibrational response of a slider. The design is particularly effective for sliders smaller than the conventional 100% slider, allowing for improved interaction with surface asperities on recording surfaces. The sensor consists of a substantial rectangular slab of piezoelectric material, which generates a charge response corresponding to in-plane stress under free boundary conditions. The enhancement is achieved by partitioning an upper conductive layer along the lines of symmetry of the slider's stress distribution. This innovative design facilitates the isolation of a high-frequency bending component, which is directly related to surface asperity interference.
