MD system limitations
The recording system in your MD recorder is radically
different from those used in tape and DAT decks and is
characterized by the limitations described below. Note,
however, that these limitations are inherent to the MD
recording system and are not a result of mechanical trouble.
“Can’t REC” is displayed before the maximum recording
time (60 or 74 minutes) has been reached
Once 255 tracks have been recorded on one MD, “Can’t
REC” is displayed regardless of the total recorded time.
“Disc Full” is displayed before the maximum number of
tracks (255) have been recorded
During Automatic track-marking, fluctuations in emphasis
within songs may be interpreted as song intervals,
increasing the total number of tracks and causing “Disc Full”
to be displayed.
The remaining recording time does not increase even
after erasing numerous short tracks
Tracks under 12 seconds in length are not counted and so
erasing them may not lead to an increase in the recording
time.
“TOC Reading” is displayed continuously
The “TOC Reading” display lasts longer than normal when a
brand new (blank) disc is inserted.
The total recorded time and the remaining time on the
MD do not total to the maximum recording time
• Recording is done in minimum units of 2 seconds each,
no matter how short the material.
• The MD recorder displays the length of the largest
continuous blank area as the remaining time. Therefore, if
there are several separate blank spaces, the remaining
time will only display a time equivalent to the largest
continuous blank space.
Tracks created through editing may exhibit sound
dropout during search operations.
Track numbers are not recorded correctly
Incorrect assignment or recording of track numbers may
result when CD tracks are divided into several smaller tracks
during digital recording.
It is not possible to erase part of a track using the A-B
Erase function
The MD recorder organizes the audio data in sound groups
and clusters. The minimum size of these units may not
consist of less than 10 seconds of stereo sound.
The correct recorded/playing time may not be displayed
during playback of MDs recorded in monaural.
Appendix
Copy protection (SCMS)
As a digital audio component, this MD recorder conforms
with the Serial Copy Management System (SCMS)
standards. The Serial Copy Management System restricts
copies made by recording digital signals to the first-
generation copies only. Therefore, an MD recorded from a
digital input source cannot be used as a source for making
another digital recording.
