Abstract:
A method of testing an inductive write element in a magnetic media read/write head, the inductive write element having electrical leads connected to a preamplifier and the inductive write element having a predetermined number of coil turns, the method comprising steps of:a) placing test probes of a test system in electrical contact with the inductive write element between the read/write head and the preamplifier; b) generating a changing magnetic field around a portion of the inductive write element inducing an electrical signal to flow through the inductive write element, through the test probes, and into the test system, the electrical signal having a current; c) measuring the current flowing into the test system; d) calculating a resistance of the inductive write element from the measured current, the predetermined number of coil turns, and the changing magnetic field.
