Abstract
A method and apparatus for improving flying height stability in a small form factor hard disk drive that typically moves at lower speeds is achieved by a slider having an ABS with an air channel and pocket. The air channel and pocket are configured to increase the amount of aerodynamic lift provided by normally smaller amounts of intake air at the inner diameter of the rotating disk and, thereby, to achieve a desired flying height profile.
