Latest Patents
One of Zhengda Pan's latest patents is titled "Crystal zone texture of glass-ceramic substrates for magnetic recording disks." This invention involves a glass-ceramic substrate that is textured using a continuous wave laser light beam. The process uniformly heats a surface zone, resulting in a continuously roughened area defined by recrystallized microcrystals. The method includes impinging a continuous wave CO laser light beam on a rotating glass-ceramic substrate, heating an annular zone to a temperature between the crystallization temperature and melting point, followed by air cooling. This technique enables a glide height of about 0.2 to 0.5 microns.
Another significant patent is "Laser-scribing brittle substrates." This invention describes a method for laser-scribing brittle substrates along a curvilinear path. It involves using at least two laser light beam spots on the substrate surface, where the first spot preheats the substrate and the second spot heats it to the laser-scribing temperature. This innovative approach allows for the formation of dual spots using crystal material or dual fiber optic cables, enhancing the precision of the laser-scribing process.
