Title: Long Van Ngo and His Contributions to Disc Drive Latch Design.
Introduction
Long Van Ngo is an inventor associated with Seagate Technology Incorporated in San Jose, California. His patent work includes mechanisms designed to secure a disc drive’s actuator and transducer when the drive is not operating, while allowing the actuator to move freely during operation. He is credited with 5 patents.
Latest Patents
Two of Ngo’s listed patents concern air-vane latch systems for disc drives.
“Air Vane Latch Incorporating a Cam Pin on the Actuator” describes a latch that uses airflow from a rotating disc to release the actuator arm during operation. When the disc stops, the vane returns to its resting position, and the latch engages the actuator to help protect it from shock. An adjustable cam pin can be rotated during assembly to rest firmly against the latch arm, positioning the actuator at its intended landing zone and reducing the need to account for accumulated assembly tolerances.
“Air Vane Latch Incorporating Top Cover Profiling” also uses airflow to move a latch vane and release the actuator while the disc is spinning. The design profiles a region of the drive’s top cover upstream from the vane, directing airflow so it produces sufficient force to open the latch during operation.
Career Highlights
Ngo’s listed inventions address practical challenges in disc drive engineering, including actuator restraint, shock protection, airflow management, and precise positioning at the landing zone. His work at Seagate reflects the role of mechanical design in improving the reliability and operation of data-storage devices.
Collaborations
Ngo’s listed coworkers include Narayanaswamy Pasupathy and Steven Kaczeus. The available information identifies them as coworkers but does not specify their roles in the patents described here.
Conclusion
Long Van Ngo’s patent work at Seagate focuses on air-vane latch designs that balance secure actuator positioning when a drive is idle with reliable movement during operation.
