Rewind
    Norewind

    Specifies that the magnetic tape that contains the backup file
    will be rewound before processing begins. The Norewind qualifier
    is the default.

    The Rewind and Norewind qualifiers are applicable only to tape
    devices. You should use these qualifiers only when the target
    device is a tape device.

    See the Oracle Rdb Guide to Database Maintenance for information
    on tape label processing.
