Protecting a recorded tape
To record-protect a tape, break off the tab for the
side you want.
To reuse the tape, cover the broken tab with
adhesive tape.
When you use a TYPE-II (CrO2) or TYPE-IV (metal)
tape, do not cover the detector slots. If you do so,
the tape deck cannot detect the tape type
automatically.
Cleaning tape heads
Clean the heads approximately once after every 10
hours of use.
If the heads become very dirty, problems such as
poor sound, low volume level, drop-out in the
sound, incomplete erasure of previous recordings,
or inability to record new material may occur.
Also, make sure to clean the heads before making
important recordings and after playing old tapes.
Use an optional cleaning cassette. For details, refer
to the instructions provided with the cleaning
cassette.
Demagnetizing the heads
Use a cassette type head demagnetizer (not
supplied) to demagnetize the heads and the metal
parts that come in contact with the tape once every
20 to 30 hours of use. For details, refer to the
instructions provided with the head demagnetizer.
System limitations of
MDs
The recording system in your MD deck has
limitations described below. Note, however,
that these limitations are due to the inherent
nature of the MD recording system itself and
not to mechanical causes.
“Disc Full” lights up before the
MD has reached the maximum
recording time (60 or 74 minutes)
When 255 tracks have been recorded on the MD,
“Disc Full” lights up regardless of the total recorded
time. More than 255 tracks cannot be recorded on
the MD. To continue recording, erase unnecessary
tracks or use another recordable MD.
“Disc Full” lights up before the
maximum number of tracks (255)
is reached
Fluctuations in emphasis within tracks are
sometimes interpreted as track intervals, increasing
the track count and causing “Disc Full” to light up.
The remaining recording time
does not increase even after
erasing numerous short tracks
Tracks shorter than 12 seconds long are not counted,
so erasing them may not increase the recording
time.
Some tracks cannot be combined
with others
Track combination may become impossible when
tracks are shorter than 12 seconds long.
The total recorded time and the
remaining time on the MD may
not reach the maximum recording
time (60 or 74 minutes)
Recording is done in minimum units of 2 seconds
each, no matter how short the material. The
contents recorded may thus be shorter than the
maximum recording capacity. Disc space may also
be further reduced by scratches.
Detector slots
(Do not cover with adhesive tape.)
