Head with an air bearing surface having a particle fence separated from a leading pad by a continuous moat

Image Number 2 for United States Patent #8199437.

A novel head includes an air bearing surface having a trailing pad adjacent the read transducer and lying in a primary plane. The air bearing surface includes a sub-ambient pressure cavity recessed from the primary plane by at least 500 nm. At least one leading pad is disposed upstream of the sub-ambient pressure cavity and has a leading pad surface in the primary plane. A moat is disposed upstream of the leading pad and is recessed from the primary plane by at least 500 nm. The moat continuously spans the entire width of the slider. A particle fence in the primary plane is disposed immediately upstream of the moat and adjacent the leading face. The particle fence continuously laterally spans at least 70% of the width of the slider.
