Laser gram load adjust for improved disk drive performance
Abstract
A new manufacturing technology that enables tight distribution of magnetic recording slider flying heights and lower slider disk spacings is described. The technique uses high intensity laser radiation to increase or decrease the suspension preload on the slider to change the flying height. The technique can be employed for tightening gram load or flying height distributions, contact avoidance or to adjust the magnetic recording capabilities of the disk drive.
