computer
to
tape. This
simply means
copying
the
program twice on the same tape
—
one
recording
right
after the other. On long clumps, one is made in one direction and the
other
one in
the
other direction. For extra safety, especially important
programs
are recorded on
more
than
one tape. Failures are rare, and your own experience should be your guide.
You may
have noticed
that
specially
wound Radio Shack Computer
Tape has no plastic
leader on
the ends. This is because when you begin "dumping" data from memory onto
tape
there
must
be real live tape there to record it.
Radio
Shack's
Computer
Tape is
of high
uniform quality, selected especially for
its low
"drop
out"
characteristics.
If one little bit of data is lost the entire
program
can be lost.
This
Tape
is wound in shorter than usual lengths, with the
C-10 being standard. It will
record
5
minutes in each direction
—
far more than enough for
the majority
of programs.
Your
entire
4K of memory can be recorded on one side of the
C-10, with the other side
quickly
available for
another
program without need for a long rewind.
Experienced
"computerists" have found from experience
that it is
better to use a separate
cassette (or at
least a separate side) for
each
program rather
than try
to
search
through long
tapes for a
desired program. Since computer
data on tape is not readable
by the human ear,
separate
cassettes
solve the problem.
Computer
Tape,
tape racks
and other recording acces-
sories are
available
at
your local
Radio Shack store.
When you are not using the Recorder for loading or recording, do not leave
RECORD or
PLAY keys down (press STOP).
Do
not expose recorded tapes to
magnetic
fields.
Avoid
placing your
tapes near the Power
Supply,
Do
not attempt to re-record on a pre-recorded Computer data tape. Even though the new
recording
process erases
the
old
recording, just
enough
information may be left to confuse
the
new recording. If you want to use the same tape a second or third time, use a high-
quality bulk
tape
eraser
to
be sure
you
erase old
data.
If
you
want
to save a taped program permanently,
break off the Erase Protect tab
on the
Cassette (see the
Tape
Recorder's Manual). When the
tab(s)
has been broken off, you can
not press
down the RECORD
key
on your
Recorder (this
will keep you from accidentally
erasing that tape).
Ground
Loops
With
some recorders, if you
leave
the
Earphone
and
Aux jack
connected
at
the same
time,
when
you make a recording,
you'll end
up with a hum added to the program (you can
hear
it
between
double-dumps).
This
is
caused
by a
ground loop in
the Recorder and cables. To
avoid
ground loop problems, keep only
the
Farphone or
the
Aux plug connected BUT NOT
BOTH.
