    摘要： A magnetic data storage system according to one embodiment includes a magnetic head; and guides on opposite sides of the magnetic head for directing a magnetic medium over the magnetic head. The magnetic head includes: outer portions each having a tape bearing surface and an array of transducers selected from a group consisting of readers and writers; and a central portion positioned between the outer portions, the central portion having a tape bearing surface and an array of transducers selected from a group consisting of readers and writers. An inner edge of each of the tape bearing surfaces of the outer portions is adapted for skiving air from the magnetic medium when the magnetic medium travels in a direction from the central portion towards the respective outer portion. The guides are oriented to direct the magnetic medium to fly over a leading one of the outer portions, engage a leading edge of the tape bearing surface of the central portion, and engage an inner edge of the tape bearing surface of a trailing one of the outer portions.
