Abstract

PURPOSE:To correct unbalance of floating amt. due to a yaw angle and to equalize floating amts. of both side rails by making a rail width on the side of narrower spacing wide than the other one. CONSTITUTION:A slider 1 is fitted with a load arm 2, and this slider 1 is formed with a rail A3 and the other rail B4 for floating so as to float on a disk with a load of 2g by the load arm 2. The rear end of the rail A3 is formed of a recording/reproducing element 5 by lithography technology, while the load arm 2 is fitted to a guide arm coupled with a head actuator. At that time, the slider is fitted with a yaw angle, e.g., 12 deg. against a track center line 6, and the width of the rail 3 is formed as, e.g., 0.26mm and the width of the rail 4, e.g., 0.30mm. By this method, the floating amt. can be kept to 0.2mum on both of the rail A3 and the rail A4 at their rear ends.

頁から２７４７頁（ＩＥＥＥ、　’ｐｒａｎｓ。In magnetic disk drives, the rail width of the slider is generally narrowed to shorten the head spacing. On the other hand, when trying to reduce the load to prevent head crashes, it is necessary to narrow the rail width in order to maintain the same spacing. However, since the thin film head has a recording/reproducing element formed at the rear end of the rail for floating, the width cannot be made narrower than that.

(1981), the spacing is reduced by creating a yaw angle with respect to the rail direction and the tangential direction of the track. This can therefore be used to reduce spacing. However, when this is done, the center of pressure within the slider shifts, resulting in different flying heights for the two rails. That is, there is a problem in that the slider floats in a tilted state and the spacing becomes a dog in the area of the recording/reproducing element where the spacing should be the smallest.

〔発明が解決しようとする問題点〕[Problem that the invention seeks to solve]
