ABSTRACT:
A slider with an intake heater near front edge heating air passing between air bearing surface and rotating disk surface to reduce change in flying height caused by water condensation. Method of operating the slider. Head gimbals assembly including slider. Head stack assembly including at least one HGA. Operating hard disk drive by receiving temperature and humidity reading to determine heater control and asserting heater control to stimulate intake heater to heat air. Embedded processor directing hard disk drive at least partly implementing operations. Embedded circuit including embedded processor. A hard disk drive including temperature, humidity sensors, embedded circuit and head stack assembly. Manufacturing methods for slider, head gimbals assembly, head stack assembly, embedded processor, embedded circuit and hard disk drive, and these items as products of their manufacturing processes.
