Abstract
A pair of opposing drive heads are positioned in a storage media drive to read and/or write a storage media interposed therebetween. Each drive head has a sensor face that includes first and second parallel longitudinally extending air-bearing surfaces. Each air-bearing surface has generally longitudinally opposing leading and trailing terminations. The storage media travels adjacent the sensor face in a traveling direction extending along the air-bearing surfaces from the leading to the trailing terminations. A drive sensor is positioned on the first air-bearing surface a distance D1 from the trailing termination thereof. The trailing termination of the second air-bearing surface extends farther a distance D2 in the traveling direction than the trailing termination of the first air-bearing surface. The drive heads are opposingly positioned such that each first air-bearing surface is opposed by the second air-bearing surface of the opposite drive head, and such that the leading and trailing terminations of the drive heads oppose each other. Each drive sensor is overlaid by the second air-bearing surface of the opposite drive head when the drive heads are aligned with respect to the…
