Title: The Innovative Contributions of Zhen Wei
Introduction
Zhen Wei is a prominent inventor based in Maple Grove, MN (US). He has made significant contributions to the field of heat-assisted magnetic recording technology. With a total of 7 patents to his name, Zhen Wei continues to push the boundaries of innovation in his field.
Latest Patents
One of Zhen Wei's latest patents focuses on calculating heater power that compensates for laser-induced writer protrusion in heat-assisted magnetic recording devices. This method involves moving a heat-assisted magnetic recording (HAMR) slider relative to a magnetic recording medium. The slider consists of a writer, a writer heater, and a near-field transducer (NFT). For various head-to-media spacings, a test tone is written to a track of the medium, which is then read to capture a Discrete Fourier Transform (DFT) of the amplitude of the read test tone. A first DFT curve is generated at the beginning of writing the test tones, followed by a second DFT curve at a saturated state. The horizontal shift between these two curves is computed to determine the writer heater power needed to compensate for NFT clearance offset due to laser-induced writer protrusion.
