| Summary: | A modified version of Chevron type Magnetoresistive Recording Heads (MRH) sensor is described. Two shielded ferromagnetic thin-film vertical-type MRH
are biased at the linear region simultaneously using a small piece of permanent magnet chip. The biasing rotates the magnetisation vector Ms of each MRH .
through 4S· with respect to their respective current vectors J resulting in an
effective Chevron orientation of 90·. This configuration is shown to be most
effective to detect field vectors in applications such as non-destructive detection
of grain structures and loss variation in electrical steels, and in packing more
bits of information in magnetic disc storage. |
