Title: Christopher David Wiederholt: Innovator in Data Storage Technology
Introduction
Christopher David Wiederholt is a notable inventor based in Rochester, MN (US). He has made significant contributions to the field of data storage technology, holding a total of 6 patents. His work focuses on enhancing data protection and optimizing disk drive performance.
Latest Patents
Wiederholt's latest patents include innovative systems and methods for data protection during concurrent operations for multiple actuator data storage devices. This technology involves a data storage device with multiple actuators that can actuate heads over different subsets of disk surfaces. When a write command is received for one actuator, the system determines the coupling state with other actuators and inhibits write commands if a potential coupling event is detected. This approach helps prevent off-track writes and protects valuable data.
Another significant patent is for a disk drive with head fly-height compensation for disk surface variations. This disk drive features a head fly-height actuator that controls the spacing between the head and disk based on the track and specific sectors where data is read or written. The fly-height actuator, which may be a thermal actuator, adjusts the head-disk spacing to achieve optimal performance for both the selected band and sectors.
