Abstract:
A method of manufacturing a thin-film magnetic head with a magnetoresistive effect multi-layered structure using exchange coupling magnetic bias, comprising the steps of:forming the magnetoresisitive effect multi-layered structure; and providing the exchange coupling magnetic bias to said magnetoresistive effect multi-layered structure by an annealing process, said annealing process including a step of gradually decreasing the temperature of said multi-layered structure to a first temperature under application of magnetic field in a particular direction; wherein said gradually decreasing step is a step of decreasing the temperature of said magnetoresistive effect multi-layered structure to the first temperature at a cooling rate with a range of 100Â° C./hour to 50Â° C./hour under application of magnetic field toward the particular direction.
