Claim 13:
14. A method comprising:
sending a write signal to cause a magnetic write transducer to write single tracks of encoded user data at a time to a magnetic disk, the magnetic write transducer having a first crosstrack width and integrated into a recording head;
activating a first crosstrack segment of a magnetic erase transducer integrated into the recording head to simultaneously erase multiple tracks of the encoded user data from the magnetic disk, the magnetic erase transducer physically and electrically separate from the magnetic write transducer in the recording head, the first crosstrack segment having a second crosstrack width at least two times larger than the first crosstrack width; and
activating a second crosstrack segment of the magnetic erase transducer different from the first crosstrack segment to erase at least one other track of the encoded user data from the magnetic disk at a width that is different than the second crosstrack width.
