The
secret
of

success
lies

and the
focused-field
recording
systern-
The core
of this quality
head is
made
of
single
crystal
ferrite
and is mounted
and
set
in
glass.
The superior
high

are contributable
to
the
structure
of
the
head gap
which
focuses
the
magnetic
field into a
sharp
oblong
radius. This
focused-field
recording
system minimizes
high
frequency
loss,
eliminates
undue
equalization
and
achieves a
wider dynamic
range.
