Abstract:
An asymmetry is determined of a signal generated by a read transducer in proximity to a changing magnetic field of a magnetic media. In response to determining the asymmetry of the signal, a current flowing through a heater of the read transducer is adjusted to cause a change to a magnetic field generated by the current. The change to the magnetic field generated by the current reduces the asymmetry of the signal.
