[0024] Referring to the drawings, FIG. 1 is a pictorial representation of a disc drive 10 that can use a recording head constructed in accordance with this invention. The disc drive 10 includes a housing 12 (with the upper portion removed and the lower portion visible in this view) sized and configured to contain the various components of the disc drive. The disc drive 10 includes a spindle motor 14 for rotating at least one magnetic storage medium 16. At least one arm 18 is contained within the housing 12, with the arm 18 having a first end 20 for supporting a recording head or slider 22, and a second end 24 pivotally mounted on a shaft by a bearing 26. An actuator motor 28 is located at the arm's second end 24 for pivoting the arm 18 to position the recording head 22 over a desired sector or track of the disc 16. The actuator motor 28 is controlled by a controller, which is not shown in this view and is well known in the art.
