Abstract:
A magnetic disk apparatus comprising:a plurality of coaxially arranged magnetic disks having respective opposite surfaces and tracks arranged on said surfaces;a magnetic head assembly including a rotatable head carriage with a hub and a plurality of head arms extending from the hub in a line, each of the head arms having a longitudinal central axis;at least one floating slider having a body configured in a generally rectangular parallelepiped shape carried by each of the head arms and having at least one magnetic head for access of one of the surfaces of the magnetic disks;said body having a longitudinal central axis extending generally parallel to the longitudinal central axis of the associated head arm and a first surface adapted to face the surface of the magnetic disk, and at least two parallel rails arranged on the first surface of the floating slider, extending obliquely to the longitudinal central axis of the body and defining a rail angle between said rails and a tangent line of a corresponding one of said tracks over which said body is positioned, wherein said rail angle is substantially zero when said body is positioned over an innermost track and said rail angle increases as said body moves radially away from said innermost track; andwherein said longitudinal central axis of said body coincides with a tangent line of an intermediate track when said body is positioned over said intermediate track.
