Abstract
A floating head device has a floating surface for imparting a floating force for floating from a recording surface by air flow formed between the floating surface and the recording surface and a suction surface for imparting a sucking force in a relative movement of a head slider to the recording surface of a recording medium. The air inlet end of the suction surface has grooves and is disposed in down-stream of the air flow from the air inlet end of the floating surface.
