Latest Patents
One of her latest patents is titled "Disk drive and control method thereof." This invention aims to reduce the structural stress applied to a head, achieving effective control when adjusting the clearance between the head and a disk using a heater. The hard disk controller/microprocessing unit (HDC/MPU) plays a crucial role in controlling the slew rate of the heater during Thermal Fly Height Control (TFC). By adjusting the output of electric current or voltage applied to the heater based on processing conditions, the invention minimizes head stress and enhances TFC effectiveness. Another notable patent under her name addresses the reduction of errors caused by the aged deterioration of the heater. The TFC controller measures the resistance value of the heater at predetermined intervals and determines if it falls within a reference range. If the resistance value is outside this range, the TFC controller initiates error handling procedures, notifying the host of any detected abnormalities.
