摘要： A magnetic disc unit includes a rotating disc type magnetic disc having an outer periphery, and a carriage arm linked to a head support mechanism for a recording/reproducing head. A base has an outer periphery and mounts the rotating disc type magnetic disc and the carriage arm, and has a side wall with an inner wall surface having an opening for inserting the carriage arm. The inner wall surface of the side wall defines a shroud surrounding the outer periphery of the magnetic disc, except at the opening in the side wall where the shroud is projected inwardly so as to decrease an opening angle of the opening in the side wall. A gap between the outer periphery of the magnetic disc and the shroud is set in a range not less than 0.1 mm but not greater than 0.6 mm.

摘要： 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.
