<p>An improved arcuate scanning head assembly (ASHA) is angled relative to the line of travel of the tape. The relative sizes of the angle, the diameter of the ASHA and the amount by which the heads protrude from the cylinder end face of the ASHA are such that the magnetic heads make firm contact with the tape when above one side of the ASHA's rotating cylinder face, but at most grazing contact with the tape when above the other side of the cylinder face. Preferably, they make firm contact on the one side and do not make contact at all when on the other side. Preferably, the angle also is such that on the side making contact, the head makes and loses contact with the tape a small distance in from the edge of the tape, reducing or eliminating problems due to the head striking the edge of the tape. Alternatively, the ASHA is left straight, but the tape cartridge for use with the ASHA is modified so that the tape is presented at an angle across the media access opening.</p> |
