Latest Patents

One of Ximin Shan's latest patents is titled "Serpentine seeks during data storage device idle periods." This invention addresses the management of data storage devices during extended idle conditions when host access commands are not being received or serviced. The patent describes an apparatus and method where a control circuit identifies a selected data transducer and its initial radial position on a rotatable data recording surface. During idle conditions, the control circuit performs a serpentine seek operation, gradually advancing the data transducer across the recording surface. This operation minimizes the risk of damage from thermal asperity contact events and other wear-related issues.

Another significant patent by Shan is "Selecting servo controller based on predicted position error signal spectrum." This invention involves determining a discrete Fourier transform (DFT) of a position error signal (PES) of a read/write head. By analyzing the PES and sensitivity functions associated with various controllers, the system selects the most appropriate controller based on deviation metrics. This innovation enhances the servo control of the read/write head, improving the overall efficiency of data storage devices.
