Subcodes
With OAT tapes.
in
addition to the recorded music signal. various subcodes are recorded
on
the tape to
aid
in
music selection and editing.
With commercially available OAT music tapes. subcodes are prerecorded on the tapes. With
blank tapes that you record yourself. subcodes are automatically recorded during recording
and
can also
be
recorded manually during editing.
• ST-IO (Start
10)
This signal
is
recorded
at
the beginning
of
each tune.
By
searching
for
this signal, the unit can lo-
cate the beginning
of
a designated tune.
Also, the tune number
for
each tune is
written
on the tape
at
the same position
as
the ST-IO. There-
fore, if the ST-IO
is
not
written
at
the proper pOSition, the tune number will not
be
displayed correctly.
• The ST-IO
is
automatically
written
on the tape during recording in the following cases:
1. When sound
is
detected again after a blank section
of
2 seconds or longer occurs during
recording.
2. When recording starts and sound
is
detected after recording
was
stopped or paused.
• Depending on the contents
of
the source being recorded, ST-IOs may
not
be written correctly
on the tape (in cases such as when there
is
excessive noise between tunes, when the interval
between tunes
is
short,
when
the sound stops and then starts again in the middle
of
a tune,
or
when
a tune contains a section
of
extremely
low
level sound!. In such cases, you will need
to edit the subcodes later. (See page
24.)
• A ST-IO cannot
be
written within 9 seconds after the previous ST-IO.
• ENO-IO
This signal
is
recorded
to
indicate the end
of
the recorded contents. The
unit
stops automatically
when
this signal
is
detected during playback
or
fast-forwarding.
This signal
is
also handy
for
quickly locating the end
of
a recording
when
continuing a recording
from the end
of
the previously recorded contents.
• If recording
is
continued from the end
of
a previous recording
that
has no ENO-IO, the total
elapsed time may
not
continue into the
newly
recorded section.
In
such a case, the total elapsed time
for
the newly recorded section will
not
be
displayed and
the tune search function may
not
operate correctly. Always
write
an
ENO-IO at the end
of
a
recording.
END-ID
Non-recorded
section
Next recording
If a non-recorded section exists,
the total elapsed time signals
wilt not be connected.
• Make sure there
is
at least 9 seconds between the last ST-IO and the ENO-IO.
