Abstract

PROBLEM TO BE SOLVED: To enable a larger capacity and a smaller size by providing one piece of head arm and suspension with a slider part embedded with two head parts in upper and lower slider surfaces and arranging these two head parts in such a manner that the head parts are capable of accessing the surfaces facing each other of two magnetic disk media. SOLUTION: The one slider part 12 consists of a structure having the two head parts and slider surfaces in its vertical direction so that the two medium surfaces facing each other of the two magnetic disk media 13 may be accessed by only one piece of head arm part 10. The front of the one piece of head arm part 10 is provided with the slider surfaces embedded with the head parts facing the magnetic disk media as a pair, by which the floating of the slider part using air bearings is eventually executed from the vertical direction. The stabilization of the heads in the stable state is made possible by the constitution decreased in the components and the spacing between the magnetic disk media may be reduced.
