As much as greater be
the surface of the engraved trail will also be greater the quantity of
particles of flux-producing and therefore the output voltage will be increased
at the terminals of the reproduction head.
Increasing the air gap
length increases the output voltage, but, in return, the response at high
frequencies will be reduced. In practice, the design of the reproduction heads
will always be made taking into account the compromise between the signal level
and the frequency response.
