ABSTRACT:
A magnetic recording and reproducing apparatus having a magnetic disk, a magnetic head and a magnetic head supporting device. The surface roughness R.sub.max of the magnetic disk is at most 10 nm, and the magnetic head has a slider on which reading and writing elements are mounted. The slider is of a generally rectangular prism shape with the entire area of a medium opposing surface which opposes the magnetic disk being flat. The surface area of the medium opposing surface is 2 mm.sup.2 or less. The apparatus has a first relative speed at which the frictional coefficient between the magnetic disk and the magnetic head is changed from a high value to a low value when the speed increases, and a second relative speed at which the frictional coefficient is changed from a low value to a high value when the speed decreases. A ridge portion between the front surface and the medium opposing surface has a round corner, wherein the length of the round corner in the direction of the medium opposing surface is larger than the length of the round corner in the direction of the front surface.
