Abstract:
Static numerical simulations of two sub-ambient pressure recording disk drivers are present, which flying height is 50 nm. The Fukui-Kaneko model is introduced in the Reynolds equation, which reflects the rarefaction affection of decreased flying height. The control volume method is employed to discrete the modified Reynolds equation, and alternative directions iterate method is used to solve the resulting discretion equation. The results show that optimization design can improve the sub-ambient pressure slider’s static characteristics. It is also demonstrated that the depth of recess affects the air bearing greatly.
