Method for providing a magnetic recording transducer
Abstract:
A method for providing a magnetic recording transducer is described. The method includes providing a pinned layer for a magnetic element. In one aspect, a portion of a tunneling barrier layer for the magnetic element is provided. The magnetic recording transducer annealed is after the portion of the tunneling barrier layer is provided. The annealing is at a temperature higher than room temperature. A remaining portion of the tunneling barrier layer is provided after the annealing. In another aspect, the magnetic transducer is transferred to a high vacuum annealing apparatus before annealing the magnetic transducer. In this aspect, the magnetic transducer may be annealed before any portion of the tunneling barrier is provided or after at least a portion of the tunneling barrier is provided. The annealing is performed in the high vacuum annealing apparatus. A free layer for the magnetic element is also provided.
