Patent ID: 7957104

Claim:
A disk drive comprising: a disk adapted to be rotated; and a flexure including a flexure body comprised of a first material layer with a first coefficient of thermal expansion and a second material layer with a second coefficient of thermal expansion that is less than said first coefficient of expansion, wherein said second material layer is affixed to said first material layer either conformally or in a patterned form or in a form having a variable thickness; and wherein a slider having an air bearing surface and including a reading and writing element is coupled adjacent to the first material layer of the flexure and wherein an increase in an ambient temperature of said flexure is accompanied by a corresponding increasing temperature of said first material layer and said second material layer and wherein a decrease in an ambient temperature of said flexure is accompanied by a corresponding decreasing temperature of said first material layer and said second material layer, whereby, as a result of differential thermal expansions of said first material layer and said second material layer said slider is elevated with increasing temperature and lowered with decreasing temperature of said first and second material layers to achieve a constant flying height.
