Just about any CD creation software will let you read in a CD (usually
cinsidered a master) and make an image of it on the HD for later use
of duplication.

You cannot use conventional techniques (as you would with floppy
drives or hard drives) to just read a sector then write it out.
Information is stored in a standard ISO format.  Along with this (and
although it isn't apparent by doing a directory of the CD) all of the
information is actually stored in single sector on the CD (this is
used to seperate the different ISO type for PC's, MAC's, Video and
audio tracks.

Writing to a CD can be VERY dependant on the drive itself.  I would
hope that the cd-burner came with some software for doing these types
of operations.

If you are really want to write your own software, you will most likly
have to contact ISO to get the format information.  As this
information is copyrighted and is sold by the ISO (and it definatly
can be VERY pricy dependying on the information in it), it is very
doubtfull that you will find it anywhere on the net.

If you are adament about copying public domain CD's and plan on
duplication several over the course of time, I would look into getting
Corel's CD creation software.  Its a very complete package and will do
exactly what you want. (I really recommend getting this software over
writing it...it will probably be a LOT cheaper considering ISO prices
and it won't take you several months and 30-40 test CD's to get it
right).

(also check of the duplication restrictions and/or licensing formation
on shareware CD's and some information such as the installation
programs or other special items may be copyrighted by the
manufacturers and/or distributor of the CD).
