Rules for digital recording
Guide to the serial copy management system
Since your MD unit uses the Serial Copy Management System
(SCMS), MDs recorded through the digital input terminal cannot be
used to make subsequent copies to other MDs through the digital
output terminal. The following diagram shows a system for making
copies through the digital or analog terminals.
Rule 1
You can record digital source (CD, premastered MD, and DAT
equipment with a sampling frequency of 44.1 kHz) to a recordable MD
through the digital input terminal.
However, you cannot make subsequent copies from the recordable MD
to other recordable MDs through the digital output terminal.
Subsequent copies can only be made through analog output terminal.
System Limitation
The recording system in your MiniDisc recorder is radically different
from those used in cassette and DAT decks and is characterized by the
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 even before the disc has reached the
maximum recording time (60 or 74 minutes)
When 255 tracks have been recorded on the disc, "Disc Full" lights up
regardless of the total recorded time. More than 255 tracks cannot be
recorded on the disc. To record new tracks, erase unnecessary tracks or
use another MD.
•
"Disc Full" lights up before the maximum number of tracks is
reached
Fluctuations in emphasis within tracks are sometimes interpreted as
track intervals, incrementing the track count and causing the "Disc
Full" indication to light up.
•
The remaining recording time does not increase even after
erasing numerous short tracks
Tracks of under 12 seconds in length are not counted and so erasing
them may not lead to an increase in the recording time.
•
Some tracks cannot be combined with others
Track combination may become impossible when tracks are edited.
•
The total recorded time and the remaining time on the disc may
not total 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.
•
Track created through editing may exhibit sound dropout
during searching operations.
•
Track numbers are not recorded correctly
Incorrect assignment or recording of track numbers may result (1)
when CD tracks are divided into several smaller tracks during digital
recording, or (2) when certain CDs are recorded with both the LEVEL-
SYNC indicator on and automatic track marking function on.
•
"TOC Reading" appears for a long time
If the inserted recordable disc is bland new, the "TOC Reading"
appears on the display longer than those that have been used.
