1. A recording head, comprising:
a magnetic write transducer having a first crosstrack width operable to write a single track of data at a time to a magnetic disk; and
a magnetic erase transducer separate from the magnetic write transducer, wherein the magnetic erase transducer is aligned with and offset from the magnetic write transducer in a crosstrack direction, the magnetic erase transducer comprising two or more crosstrack segments that can be individually activated, the two or more crosstrack segments having different crosstrack widths, at least one of the different crosstrack widths corresponding to a second crosstrack width operable to simultaneously erase multiple tracks of data from the magnetic disk.
