Introduction

James E. Donaldson 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 3 patents. His work primarily focuses on enhancing the efficiency and synchronization of disk drive systems.

Latest Patents

One of his latest patents is the "Disk drive spindle synchronization apparatus and method." This invention describes a data storage disk drive array that is synchronized using drives, each equipped with an onboard oscillator assembly. The system allows for either independent operation of each drive or synchronization of selected drives using a common or slave sync line. This sync line can supply an index signal to all or any portion of the drives in the array. The oscillator assembly of any drive in the synchronized array can serve as the source of the common precision index signal. Additionally, the system can be partitioned into subarrays, allowing for synchronization of the entire system, individual subarrays, or any combination thereof, while still enabling any drive to function independently of the synchronization of other drives.
