Abstract
The magnetoresistance effect at room temperature of thin NiFe films can be used in a reproducing head for magnetic recording systems. Different head configurations are possible: unshielded magnetoresistive element (MRE), MRE between magnetic shields and MRE in the yoke of a head. Unshielded heads can be used when long wavelength information has to be detected. Shielded- and yoke magnetoresistive heads can also reproduce short wavelength information. Some applications in audio recording systems are discussed.
