摘要： A magnetic disc device includes a magnetic disc, a magnetic head and an actuator. A ramp portion is provided for retracting the magnetic head when recording/reproducing operation is not performed. The ramp portion is arranged on a running path of the magnetic head on an external side of the magnetic disc so that a part of the ramp portion protrudes to an upper part of the outer periphery of the magnetic disc. A load-bar lubrication layer is formed on the surface of a load bar provided at the leading edge of the magnetic head. A head lubrication layer is formed on a head-slider plane of a head slider of the magnetic head. The load-bar lubrication layer reduces a dynamic friction coefficient with the ramp portion surface and suppresses occurrence of abrasion power, and the head lubrication layer suppresses adhesion of abrasion powder to the head-slider plane.

摘要： A magnetic head includes a head slider configured to float above a recording medium and having an element part for recording to and reproducing from the recording medium, the element part being situated on a medium facing surface facing to the recording medium. The medium facing surface has a first air bearing surface situated in a vicinity of a side of an air flow-out end. The medium facing surface has a rear rail having the element part situated at the side of the air flow-out end of the first air bearing surface. The first air bearing surface is covered with a lubricating layer made of water repellent resin and has an average surface roughness larger than an average surface roughness of a surface of the element part.
