Remedy 3: Place a non-metallic intermediary element of 20 to 40

mm thickness between the read-write head and the iron frame. This

will significantly reduce the parasitic coupling of the field and the

support (Fig. 5).

Remedy 4: It is also possible to contact the read-write heads via the

function block (PLC) and to use it to switch them on and off. The

influence through another read-write head can be avoided using the

selective mode, where the channel in whose transfer window the

data is located is active (see manual BL ident Proxy-Ident-Block

(PIB), D101578). Using this method the adjacent read-write heads

do not emit a field and there is no mutual interference.
