Latest Patents

Chung's latest patents include "Methods and devices for preventing potential media errors from growing thermal asperities." This method enables defect margining of a disk drive by executing a data access command on a target sector. Upon encountering a data access error, the address of the target sector is added to an error list. A thermal asperity scan is then performed, and if detected, the data stored within the margined sectors is relocated. His second patent, "Methods and devices for preventing media errors due to media scratches," involves scanning each Logical Block Address (LBA) of the disk drive to detect read errors. If a media scratch is present, data sectors associated with it are relocated to a spare location, ensuring data integrity.
