Remedy: Install the data carriers in a different manner and there will
no longer by an influence on the transfer zone (Fig. 2).
Installation of several read-write heads on metal frames or metal supports
Every read-write head which is mounted on metal couples a part of
the field to the metal support. If the minimum distance d and the
metal-free zones are observed, there is generally no mutual
influence. If however a metal frame should have an unfavourable
form an influence is still possible. This results in longer data transfer
times and error messages in the interface module.
Problem: Mutual interference of the read-write heads
