A magnetic head has a recording head that writes data to a round magnetic
disk, and a playing head that reads data. For the recording write head,
the magnetic flux density distribution around the head and the response
of the head field to input electric signals are the important characteristics
for its performance evaluation. To study these characteristics, the analysis
must include the effects of eddy currents generated on a yoke.
This example presents the use of magnetic field analysis of the recording
write head with the effects of eddy currents on the yoke, to evaluate the
response characteristic of the head field.
