Abstract
A near-field optical head comprises a slider body and a cantilever arm extending from the slider body and having a contact pad at an end portion thereof for contacting a surface of a recording medium. The slider body has an air bearing surface which interacts with a film of air moving in a direction adjacent to the surface of the record medium to generate a lift force to fly the slider body over the surface of the record medium and urge the contact pad of the cantilever arm into contact with the surface of the record medium.
