Title: Innovations of Peng Zhang in Heat Assisted Magnetic Recording Technology
Introduction
Peng Zhang is a prominent inventor based in Pleasanton, CA, known for his significant contributions to the field of heat assisted magnetic recording (HAMR) technology. With a total of six patents to his name, Zhang has been instrumental in advancing the capabilities of data storage solutions.
Latest Patents
Among his latest patents is the "Heat assisted magnetic recording write apparatus having a dielectric gap." This invention describes a HAMR write apparatus that integrates a laser, a pole, coil(s), a near-field transducer (NFT), and a dielectric gap. The design allows the pole to write to the media while the coil(s) energize the pole. The waveguide, optically coupled with the laser, directs energy toward the air bearing surface (ABS). The NFT, which includes a metal nose and a metal cap, is also optically coupled with the waveguide. The dielectric gap is strategically positioned between the NFT and the main pole, enhancing the efficiency of the recording process.
Another notable patent is the "Flat NFT for heat assisted magnetic recording." This patent relates to an EAMR head featuring a plasmonic bulk metal plate. The waveguide core has a trapezoidal cross-section, and the plasmonic bulk metal plate is placed adjacent to the short side of the trapezoid. This innovative design helps to reduce the temperature of the NFT, thereby improving the overall performance of the recording head.
