Title: Li Li’s Patented Innovations in Disc Testing

Introduction

Li Li is an inventor associated with Bloomington, Minnesota, and Seagate Technology Incorporated. Her work includes patented technologies for optical inspection and glide testing of data-storage discs. The supplied information lists 4 patents.

Latest Patents

“Near Field Optical Certifying Head for Disc Asperity Mapping” describes an optical head that flies close to a disc surface. It focuses light through an objective lens and a solid immersion lens, then uses near-field coupling to illuminate the surface. The reflected light varies with the surface condition, allowing the system to identify surface features and asperities.

“Air Bearing Slider with Increased Speed Sensitivity” describes an air-bearing slider with two asymmetrical rails separated by a cavity. A wider, hooked section on the active rail increases the slider’s flying-height sensitivity to disc and wind speed. The design also uses a wider nonactive rail to produce slight negative roll, and a vibration sensor attached to the slider supports disc glide testing.

Career Highlights

Li Li’s listed inventions address precision measurement and testing in disc-drive technology. The optical certifying head supports surface-condition assessment, while the air-bearing slider design improves sensitivity during glide testing. Both patents are associated with Seagate Technology Incorporated.

Collaborations

The supplied information identifies Ling Wang and Zuxuan Lin as Li Li’s coworkers. It does not specify their roles in the listed patents.

Conclusion

Li Li’s patent work at Seagate Technology Incorporated focuses on optical disc-surface inspection and sensitive air-bearing slider designs for glide testing.
