Abstract

The figure illustrates diagrammatically an arrangement for positioning a magnetic transducer 10 relative to a rotating magnetic disk 11 at a spacing in the range of 2-8 microns. In the arrangement shown, the magnetic transducer 10 is deposited on the trailing edge surface of slider 13 in a conventional manner. The slider 13 has a surface 14 disposed adjacent to the surface 15 of disk 11 and is spaced therefrom by a relatively thin air bearing. Surface 14 is completely flat and is not provided with any tapers or crowns at either the leading or trailing edges. The leading edge E of the slider 10 is defined by surface 17 of the slider and surface 14 which are substantially at 90Πto each other. A very light load, e.g., in the order of 1 gram, is applied to the slider in the area immediately above the leading edge E.

Head Slider and Load-Achieving Air-Bearing Suppression Associated With Low Head Load

The figure illustrates diagrammatically an arrangement for positioning a magnetic transducer 10 relative to a rotating magnetic disk 11 at a spacing in the range of 2-8 microns. In the arrangement shown, the magnetic transducer 10 is deposited on the trailing edge surface of slider 13 in a conventional manner. The slider 13 has a surface 14 disposed adjacent to the surface 15 of disk 11 and is spaced therefrom by a relatively thin air bearing. Surface 14 is completely flat and is not provided with any tapers or crowns at either the leading or trailing edges. The leading edge E of the slider 10 is defined by surface 17 of the slider and surface 14 which are substantially at 90OE to each other. A very light load, e.g., in the order of 1 gram, is applied to the slider in the area immediately above the leading edge E.

It has been found desirable to also apply a substantially smaller force to the trailing edge, e.g., one-tenth, of the force applied to the leading edge to improve the stability of the slider 13.

The loading force for the slider may be obtained by a cantilevered leaf-type spring arrangement 18 which is also provided with a torsional force T to load the trailing edge of the slider.

It has also been found that if the leading surface 17 of the slider is wider than the trailing surface on which the transducer 10 is mounted, there is less tendency for the slider to twist abou...
