The Invention
The invention is directed to a magnetic head for
recording, erasing, and/or reading information from a magnetic
carrier. The two independent claims, claims 11 and 12, are
reproduced below:
11. A magnetic head comprising at least one
core portion of polycrystalline MnZn ferroferrite
material, said material having an average grain size
ranging between 0.2 and 3.0 micrometers in order to
substantially reduce output noise signals.
12. A magnetic head comprising at least one
core portion of polycrystalline MnZn ferroferrite
material, said material having an average grain size
ranging between 0.2 and 3.0 micrometers so that the
rubbing noise level is less than the electronic
noise level.
