Restrictions on MDs
Convenient Functions/Reference
Because the MD recording method has some restrictions, the following phenomena may occur. The phenom-
ena are not a malfunction of this product.
Phenomenon
"DISC FULL" appears even though
recordable time as printed on the MD
remains.
"DISC FULL" appears even though
the track numbers and recordable
time have not reached the limit.
You cannot join tracks or groups.
The remaining recordable time does
not increase even after you have
erased some tracks.
Sound drops out intermittently during
fast forward or fast reverse.
Recorded time plus remaining time is
shorter than the total recordable time
printed on the MD.
Serial Copy Management System (SCMS)
The Serial Copy Management System protects copyright and allows only first-generation digital copies from
the digitally recordable source.
CAUTION
• The SCMS does not permit you to record sound from a digitally recorded MD to other media as digital sound.
High Speed Copy Management System (HCMS)
You can record sound to an MD at a higher speed than normal recording. Therefore, restrictions are
required in order to protect copyright.
When you use this product to record a track of a CD with the high speed recording function, this
product does not then permit you to use the high speed recording function to record the same track of
the CD to an MD within 74 minutes of the start of the first recording.
For instance, when you record the track 1 of a CD to an MD with the high speed recording function,
you cannot record the track 1 again to an MD with the high speed recording function for 74 minutes
after the first high speed recording started. In addition, you cannot record 101 or more tracks within 74
minutes with the high speed recording function.
Regardless of remaining recordable time, MDs have a limit on the number of
recordable tracks. You cannot record 255 or more tracks to an MD. (You can
record up to 254 tracks to an MD.)
Repeated partial erasure and recording creates many blanks on an MD.
When you record a track to such an MD, the track is split up and a small portion
of the track is recorded into each blank.
When the number of such split portions increases, "DISC FULL" may appear.
When a split portion is 8 or less seconds (in SP mode (the standard stereo
recording mode)), you cannot join the track with another track.
In addition, when you erase such portions, remaining recordable time does not
increase.
With a track split into many portions, fast forward or fast reverse may produce
intermittent sound dropouts.
You cannot join tracks that have different MDLP modes (SP/LP2/LP4).
MD recording is possible only when there is a blank of consecutive 12 or more
seconds (in SP mode) on the MD. Actual recording time is shortened on an MD
that contains many blanks.
