Abstract
A flying head slider has gas bearing rails formed on a surface thereof disposed in opposed relation to a recording medium. The flying head slider flies at a microscopic distance above the recording medium by a pressure produced by a stream of gas resulted from the rotation of the recording medium. Each of the gas bearing rails comprises an inflow portion disposed at an inflow side of the gas stream so as to produce a pressure, an outflow portion disposed at an outflow side of the gas stream so as to produce a pressure, and a connective portion interconnecting the inflow portion and the outflow portion in a common plane. The connective portion serves to suppress an excessive compression of the gas, and achieves good damping characteristics.
