Claims

[Claims for Utility Model Registration] (1) A contact surface that contacts the magnetic disk from the side opposite to the magnetic head, and a radial direction formed on this contact surface at a position facing the magnetic head and extending in the radial direction. In the pad having a groove, the contact surface is formed to be inclined toward the outer periphery in a direction away from the magnetic disk, and the radial groove is formed in this inclined contact surface, and further in the radial direction. The groove has a constant width on the outer periphery,
A pad for a magnetic disk device, characterized in that an inner circumference gradually widens inward. (2) The pad for a magnetic disk device according to claim 1, wherein the contact surface of the pad is formed in a flat shape extending parallel to the magnetic disk near the inner peripheral edge. (3) The pad for a magnetic disk device according to claim 1 or 2, wherein the widened radial groove portion of the pad is formed inward from the innermost track position.
