"Linked" multisession disks vs. normal multisession disks

I read that there are two different kinds of multisession disks. There's the
normal kind where each time you write a new session it wastes a little space
in order to close and start the session. Then there's another kind where it
"links" the old session in so that it doesn't waste space. Is it true that
linked multisession doesn't waste space, and how do you choose what kind of
multisession disk you are going to make in Nero or Roxio?

Let's go slow here. First, learn how to make multisession cd with Nero:

Please see one of the usual references: the CD-R FAQ or the primer at my
WWW site on multisession and packet writing / UDF.

Briefly: writing variable-length packets allow you to write multiple
times before closing a session. While the session is open, the disc can
be read only in a writer in an OS that has packet writing installed.
Though there is a theoretical capability for leaving a mastered session
open, in practice software does not handle that well. Therefore, any
data mastered to a disc will be in a discrete session.


Closing a session requires 'wasting' space for the runout/leadout, but
then the disc is readable in any CD-ROM drive if it was mastered. If
variable-length packets were closed to ISO 9660 Level 3, a modern OS
will read the disc without trouble. If closed to UDF 1.5, either packet
writing or UDF reader software is required.

Finally, to the extent that a fixed-length packet disc can be closed, it
is closed when written and there is no signficance to "session" on such
a disc.

And, yes, that is a very brief overview. The references will fill in the
rest.
