  • Publication number: 20010040759
    Abstract: A magnetic tape apparatus for reading data from and writing data to a magnetic tape has a magnetic head for reading or writing the data, and first and second tape guides. The first tape guide has a first guide surface to guide the magnetic tape, and the first guide surface has a width that is narrower than the width of the magnetic tape. The second tape guide has a second guide surface to guide the magnetic tape, and the second guide surface has a width that is wider than the width of the magnetic tape. If the tape moves laterally against a flange on the first tape guide, the flange initially yields to the pressure of the tape. Then the flange presses against the magnetic tape to return the tape to a laterally aligned position along a tape path.
