Present and future development of laser micro-processing on disk substrate——laser texture

DUAN Jun

Laser double texturing of metal and non-metal substrate disks is introduced.The difference between the laser and traditional technique,application,process and mechanism are also introduced.This technique employs Nd:YVO4 or CO2 laser to provide a high repetition rate short-pulsed laser acting on the inner circle substrate surface of the disk,change the surface topographical feature and create a great number of bumps with rounded protrusions.The laser texture zone provides a precision contact start/stop zone for the contacting slider.
