Abstract
Methods of removing a magnetic domain from a slider structure, such as a shield in a write head, in a data storage assembly. The method comprises passing the slider structure in close proximity to a decaying magnetic field of at least 100 Oe and no more than 1500 Oe originating from within the storage assembly. In some implementations the decaying magnetic field has an oscillating polarity.
