Title: The Innovative Contributions of Benjamin Geunbae Ryu
Introduction
Benjamin Geunbae Ryu is a notable inventor based in Cupertino, CA. He has made significant contributions to the field of data storage technology, holding a total of 6 patents. His work primarily focuses on methods that enhance the performance and reliability of disk drives.
Latest Patents
One of Ryu's latest patents is a method for determining read/write head position based on phase detection of a servo pattern. This innovative method allows for the precise determination of the RW head's radial position relative to tracks within a magnetic data disc. It involves sensing both an S-burst signal and a P-burst signal with the RW head. The S-burst signal maintains a constant phase across tracks, while the P-burst signal rotates radially. By analyzing the phase difference between these signals, Ryu's method effectively determines the RW head's position.
Another significant patent is an algorithm to detect the touchdown of the flying head on a disk. This invention pertains to a disk drive that utilizes a fly-on-demand head (FOD) and a process for determining contact between the FOD head and the disk. The head is equipped with a heating coil that can receive various power levels. The process includes generating estimate error data and variance values for different power levels to accurately determine the contact point between the head and the disk.
