ABSTRACT:
A magnetic disk apparatus comprising magnetic disks and a magnetic head assembly including a rotatable head carriage with a hub and head arms extending from the hub in a line. A floating slider is carried by each of the head arms and the sliders have magnetic heads for access to the surfaces of the magnetic disks. Parallel rails are arranged on the surface of the floating slider facing the associated surface of the magnetic disk. The floating slider has a longitudinal central axis extending generally parallel to the longitudinal central axis of the associated head arm and the rails extend obliquely to the longitudinal central axis of the body. The floating slider is arranged so that, when the floating slider is positioned on the innermost track, the angle the rails form with the tangent to the innermost track is substantially zero, so as to reduce the variation in the flying height of the floating slider from the magnetic disk, without reducing the recording capacity.
