Abstract
PURPOSE: To reduce the sliding abrasion of recording media and perform good recording and reproducing by making the radius of curvature of slider contact face to values of a specified range and gently and continuously changing the radius of curvature toward the circumferential edge part.
CONSTITUTION: The radius of curvature R1 of the contact of face of a slider 4 in the sliding direction of a medium 1 is 3 to 20m and the radius R1 continuously changes so as to become a smooth curve toward the circumferetial edge part chamfered at a radius of curvature R3. The contact face rectangular to the sliding direction is 0.3 to 5m in radius of curvature R2 and is formed with a similar smooth and continuous curved face. When this slider 4 makes pressure contact to the medium 1, the contact pressure is dispersed by the curved face of the circumferential edge part of the radius of curvature R3 and even if a change in the posture of the slider 4 occurs, shaping away of the medium surface does not occur and the sliding abrasion decreases. In addition, even if the posture of the slider 4 changes owing to the spherical face formed by the specified radii of curvature R2, R3 of the contact face, no clearances are produced between the recording-reproducing core and the medium, thus good recording and reproducing are accomplished.
