Air bearing in hard disk platters.

[Jcruz]

Hi, I'm looking for complete information on how the air bearing is generated in the plates due to the rotation. I am definitely studying what impact any physical modification of the platters has on the generation of this air, so crucial for head reading. For example, "how much flat" have to be for everything to work properly. Does anyone know a good site where can find this information? I only find small mentions to the air bearing.

Thanks
