Latest Patents

One of his latest patents is titled "Recessed write gap material for enhanced bias current injection and maximizing aerial density capacity in perpendicular magnetic recording." This invention relates to a magnetic write head structure that improves the maximum allowable bias current, thereby maximizing the current-assisted areal density capacity (ADC) gain in hard-disk-drive storage devices. The write head includes a magnetic main pole (MP) and a trailing shield (TS) made of magnetic material, which collects back the magnetic flux. The write gap (WG) between the MP and TS is comprised of a non-magnetic electrical conductor, designed to increase the electrical contact area for bias current flow.

Another notable patent is "Tapered optical and magnetic elements for improved writing in heat-assisted magnetic recording." This invention involves writer head products for heat-assisted magnetic recording devices and methods of making the same. The writer heads consist of multiple layers, including a waveguide blocking layer, a waveguide layer, a near-field transducer layer, a heat sink layer, and a peg layer. Each layer may feature a tapered angle near the air-bearing surface, enhancing the efficiency of the writing process.
