TAPE
SPLICING
AND
EDITING
Cut
the
tape
diagonally
with
an
overlap
so
that
the
ends
are
lined
up.
Cutting
tape
on
the
diagonal
eliminates
detection
of
the
splice
in

Cover

splicing
tape,
exerting
pressure
to
secure

evenly.
Trim
off
excess
splicing
tape.
Cutting
into
magnetic
tape
very
slightly
will
eliminate
the
possibility
of
a

Splicing
using

requires
skillful
work.
For

recommended.

CLEANING
Heads
The

Heads
do
not require
a
great
deal
of
cleaning,
However,
if
old
tapes
or
tapes
which
have
been
spliced
are
used,
GX
head
cleaning
is
also
recommended.

Pinch
wheel
and
capstan
If
foreign
matter
is
allowed
to
accumulate
on
the
pinch
wheel
and
capstan,
these
particles
will
come
off
on
the
tape
causing
deterioration
of
sound
quality.
Oil
adhering
to
the
capstan
also
causes
irregularity
in
tape
transport.
Therefore,
it
is
also
recommended
that
these
parts
be
wiped
clean
periodically.

HEAD
DEMAGNETIZING
Prolonged
use
of
the
machine
will
gradually
build
up
residual
magnetism
on
the
heads,
The
effect
of
magnetiza-
tion
is
that
it
causes
a
considerable
drop
in
high
frequency
response
and
introduces
noise
into
your
recordings.
It
is
therefore,
recommended
that
head
demagnetizing
be
per-
formed
periodically.
This
can
be
accomplished
with
a
bulk
head
demagnetizer
by
bringing
the
prongs
of
the
demag-
netizer
close
to
the
heads
and
making
several
small
circular
motions
over
all
head
surface
areas
as
well
as
the
head
housing.
*
Turn
off the
power
of
the
unit
prior
to
demagnetizing
the
heads.
Do
not
use
magnetized
tools
in
the
vicinity
of
the
heads
and

Do

and,
if
necessary,
readjust
as
follows:
1.
DISCONNECT
