Abstract

The figures disclose an improved design for a compliant guide for magnetic tape, such as that utilized in tape storage systems. As shown in Figs. 1 and 2, the guide is comprised of a plurality of spring members extending individually from a base member. At the end of each spring member a pad, such as that illustrated in Fig. 3, is mounted. The pad material is selected for wear properties alone, i.e., having a high wear resistance and high mechanical strength. The spring members, on the other hand, are selected for spring characteristics. In the preferred design, the spring material is fabricated of stainless steel #316, and the pads are fabricated of an alumina ceramic material. The design is beneficial also in that the separate pads individually contact the tape.

Compliant Guide Assembly With High Wear Resistance Contact Pads

The figures disclose an improved design for a compliant guide for magnetic tape, such as that utilized in tape storage systems. As shown in Figs. 1 and 2, the guide is comprised of a plurality of spring members extending individually from a base member. At the end of each spring member a pad, such as that illustrated in Fig. 3, is mounted. The pad material is selected for wear properties alone, i.e., having a high wear resistance and high mechanical strength. The spring members, on the other hand, are selected for spring characteristics. In the preferred design, the spring material is fabricated of stainless steel #316, and the pads are fabricated of an alumina ceramic material. The design is beneficial also in that the separate pads individually contact the tape. This results in the performance of the guide as a true compliant guide. The disclosed idea achieves improved load control by utilizing a flat spring with an offset preload (Fig. 4). The offset, spring thickness, finger length, and finger width can be chosen to minimize the load variability due to tolerances. The load variability achieved in this way is approximately half that of conventional designs with angle preload bends. If desired, the pads could be mounted for rotation with respect to the spring members in order to prevent formation of a wear line across the pads. In the embodiment illustrated, the pads are press fed with respect to t...
