Restrictions on MDs
MDs employ an original recording method different from those used for cassette tapes and digital audio 
tapes. Because the MD recording method has some restrictions, the following phenomena may occur. The 
phenomena are not a malfunction of this product.
You can make a clear digital recording from a CD to an MD. However, you are prohibited from duplicating the 
digitally recorded sound from that MD to another MD using the original digital signals. In short, you cannot 
make "a copy of a copy". This rule is called the Serial Copy Management System (SCMS). This product is 
designed to comply with this rule.
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.
• You cannot digitally record a digitally recorded CD-R/CD-RW to an MD. "SCMS CANNOT COPY" appears and the 
digital sound is converted to analog.
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 permit you to use the high speed recording function to record the same track of a CD 
to an MD within 74 minutes of the start of the first recording.
For instance, when you record the first track of a CD to an MD with the high speed recording function, 
you cannot record the same track to an MD for 74 minutes after the first high speed recording started. 
In addition, when recording tracks from a CD with the high speed recording function, you cannot 
record 101 or more tracks within 74 minutes after recording starts. You can record up to 100 tracks in 
such a case.
Phenomenon
Possible cause
"DISC FULL" appears even though 
recordable time as printed on the MD 
remains.
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.)
"DISC FULL" appears even though 
the track numbers and recordable 
time have not reached the limit.
Repeated partial erasure and recording creates numerous time 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 inserted into each time 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 it with another track.
In addition, when you erase such portions, remaining recordable time does not 
increase.
With a track split among many time blanks, fast forward or fast reverse may pro-
duce intermittent sound dropouts.
You cannot join tracks that have different MDLP modes (SP/LP2/LP4).
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.
MD recording is possible only when there is a time blank of 12 or more seconds 
consecutively (in SP mode (the standard stereo recording mode) ) on the MD. 
Actual recording time is shortened on an MD that contains numerous time 
blanks.
