Latest Patents

One of his latest patents is titled "Glide testing of disks with calibration confirmation testing by inducing collision of the slider with production disk surface." This method presents a way to test the glide head fly-height by inducing a collision between the glide head and a disk under test. The glide test system is initially calibrated using calibration disks, and the method periodically tests the calibration without interrupting production testing. This is achieved by lowering the rotation rate until the glide head collides with the rotating disk surface. The rotation rate at which the collision occurs is then compared with the expected value based on knowledge of disk samples and the initial calibration. Parameters for acceptable high and low values are established to detect changes in the glide test system performance, triggering automatic or manual recalibration.

Another significant patent is the "System, method, and apparatus for in-situ acoustic emission monitoring of burnish heads in production during magnetic media cleaning or burnish process." This in-situ technique monitors the acoustic emissions of burnish heads while they clean or burnish magnetic media. The burnishing process is controlled to identify interactions or contact between the head and media, which may indicate burnish head damage or other issues. A piezoelectric sensor mounted on the burnish arm gathers amplified signals as acoustic emissions, alerting operators to abnormal conditions.
