As one disc approaches its maximum capacity, the other drive
begins recording, so that for a period, both drives are recording
the same programme. The precise sequence of events is as
follows:
The record level on the second drive is ramped up from
zero (to the preset level), over the period set as the Fade-
In Time in the DiscSpan submenu
Both drives continue in record at full level for the period
set as the Overlap Time in the DiscSpan submenu
Finally, as the first drive reaches its maximum capacity,
its record level ramps down to zero over the period
defined as the Fade-Out Time in the DiscSpan submenu.
Recording now continues as normal on the second drive
This is illustrated below.
Track IDs are recorded on the two discs as shown, to allow the
CDR-882 to synchronise the two discs on playback. Although
the fade-in and fade-out times can be set as low as 1 second,
the track length for the fade will never be less than 4 seconds to
adhere to the Red Book standard. The minimum time for overlap
is 4 seconds.
It is also possible to initiate the change-over from one drive to
another manually if wished, to take advantage of natural pauses
or breaks in the programme being recorded. To force a drive
change-over in this way, press the DRIVE SELECT button. A
confirmation message appears on the display:
Switch drive?
Enter – Yes
Press the ENTER button (the AMS knob) to perform the change-
over, or press DRIVE SELECT a second time to cancel. The
“next” drive will now begin recording almost immediately, the
fade-in time being reduced automatically to 100ms. In this
special case, the next Track ID is still recorded 4 seconds after
the start of the fade-in, to maintain Red Book compliance. The
overlap and fade-out of the first drive then continue as with
automatic change-over.

Track IDs in DiscSpan Mode
The maximum number of tracks which can be recorded on a
single CD is 99. This is a limitation laid down in the Red Book
specification. However, DiscSpan operation requires 3 Track
IDs to be recorded at the start and end of each disc in the
sequence, except for the first, which only requires 3 at the end.
As a consequence, the maximum number of tracks that can be
recorded on a CD in DiscSpan mode is 96 in the case of the
first disc in the sequence and 93 on the second and subsequent
discs.
Identing discs in DiscSpan Mode
Each of the series of discs recorded sequentially in DISCSPAN
mode has a numeric identifier to indicate its number in the
sequence. This is appended to the CD Text Title field. The default
Title is “Multi”, so the Title fields of a series of discs recorded in
DISCSPAN mode will be:
Multi-0 > Multi-0 > Multi-0 > etc.
If the user enters his/her own Title for the sequence of
recordings via the CDR-882’s CD Text facility, Multi-xx will
always occupy the last eight characters of the Title field. (See
page 45 for more information about CD Text.)
