Latest Patents

One of his latest patents is titled "Low noise magnetic thin film longitudinal media." This invention provides a magnetic thin film recording medium designed for longitudinal recording of magnetic flux transitions. The read-back signals are enhanced due to a substantial reduction in media noise, achieved through a unique vacuum deposition process. This process involves applying an underlayer to a substrate in a low temperature plasma environment, which creates voids that isolate individual grains, resulting in lower media noise levels.

Another notable patent is the "Process for manufacturing selectively textured magnetic recording media." This process allows for the controllable texturing of magnetic recording media, particularly in areas that come into contact with data transducing heads. The method includes polishing an aluminum nickel-phosphorous substrate and using pulsed laser energy to form an annular head contact band. This innovative approach significantly increases the durability of the media.
