30 September 1996 New laser texturing process of magnetic disks for stiction reduction

Microscopic bumps of heights being tens of nm can be produced on a smooth nickel-phosphorus disk substrate using Q-switched laser pulses from a diode-pumped laser. This technique is being used in the manufacture of high-end disk drives where tens of thousands of such bumps are produced to form a dedicated landing-zone racetrack for the magnetic head to land and takeoff without stiction.
