Latest Patents

One of Balvinder Singh's latest patents is titled "Systems and methods for testing magnetic media disks during manufacturing using sliders with temperature sensors." This patent describes a method that involves scanning the surface of selected disks using a slider equipped with a magnetic transducer and a temperature sensor. The method includes counting the number of surfaces scanned and determining if a threshold crossing event has occurred based on the temperature sensor's signal. If the number of threshold crossing events exceeds a preselected limit, the number of surfaces scanned is stored. The scanning process is stopped if the number of surfaces scanned surpasses a defined threshold, ensuring efficient quality control during manufacturing.

Another significant patent is "Disk drive calibrating bias signal for touchdown sensor." This invention involves a disk drive that includes a head actuated over a disk, featuring a touchdown sensor with a specific resistance. A bias signal is applied at a reference value to the touchdown sensor at a reference temperature, allowing for the measurement of the corresponding reference resistance. An operating value for the bias signal is generated based on various factors, including the thermal coefficient of resistance (TCR) of the touchdown sensor, which indicates how resistance changes with temperature.
