How to Burn More Than Once to DVD R: 6 Steps (with Pictures).
The reason that the TotalSpace of a CD-R is set to maximum 659 Mb is because most CD-Writers are not able to write more than this value to a CD-R (because of mechanical or firmware shortcomings). Thus bigger CD-R's are useless for these CD-Writers. Only a few CD-Writers can go beyond this 659 Mb boundary, the most common are mentioned below.
CD are OPTICAL Media while floppies are Magnetic media. Magnetics media can be written thousands of times while optical media can be written only once when it is in the form of CD R. when it is CDRW there is an extra optical coating on the disc that when burn produces pits or grovees of data. when it is erases these optical coating will melt and cover those pits and therby by making it look.
Erasing a CD is a simple process, but it can only be done with a CD-RW disk. The data on a CD-R is permanently written on the disc. You are being eco-friendly when you use a CD-RW, because you are reusing a disc rather then burning a disc that will later be thrown out when you are done with it.
Like a CD-R, a CD-RW has hardcoded speed specifications which limit recording speeds to fairly restrictive ranges. Unlike a CD-R, a CD-RW has a minimum writing speed under which the discs cannot be recorded, based on the phase change material's heating and cooling time constants and the required laser energy levels.
There is a method to write a CD-R in one go, which will be described below. One also could think of creating an extra partition and writing the image to that partition instead to a file. I vote against such a strategy because if you write to the wrong partition due to a typo, you can lose your complete Linux system. Read: that happened to me.
CD-RW (compact disc, rewriteable): CD-RW (for compact disc, rewriteable ) is a compact disc ( CD ) format that allows repeated recording on a disc. The CD-RW format was introduced by Hewlett-Packard, Mitsubishi, Philips, Ricoh, and Sony, in a 1997 supplement to Philips and Sony's Orange Book. CD-RW is Orange Book III ( CD-MO was I, while CD-R.

CD-RW: Techies sometimes buy CD-RWs for making temporary backups of data. You can write information to them, just as you can with CD-Rs. But when a CD-RW fills up, you can erase it and start over with a clean slate — something not possible with a CD-R. However, CD-RWs cost more money, so most people stick with the cheaper and faster CD-Rs.
A CD-ROM drive can only read the data from a CD whereas a CD Writer can also write (burn) data to a disk. A CD Writer uses a special type of writable CD of which there are two types, CD-Rs and CD-RWs. A CD-R (CD Recordable) disk can be written to only once but a CD-RW (CD ReWritable) disk can be overwritten many times.
CD-R (compact disc, recordable): CD-R (for compact disc, recordable ) is a type of write once, read many ( WORM ) compact disc ( CD ) format that allows one-time recording on a disc. The CD-R (as well as the CD-RW) format was introduced by Philips and Sony in their 1988 specification document, the Orange Book. Prior to the release of the.
When you write data to a CD-R, the writing laser (which is much more powerful than the reading laser) heats up the dye layer and changes its transparency. The change in the dye creates the equivalent of a non-reflective bump. This is a permanent change, and both CD and CD-R drives can read the modified dye as a bump later on.
CD-Recordable (CD-R) discs store up to 700MB of data or 80 minutes of CD-quality audio on a single disc. Verbatim CD-R discs utilize performance recording dyes for improved burning at high speeds, up to 52X, which allow you to record a CD in less than 2 minutes.
To create a writeable CD (CD-R), you need to modify the surface of a CD so you can burn data onto it, turning it into a CD-R. There are no bumps on a CD-R. A clear dye layer covers the CD's mirror. A write laser heats up the dye layer enough to make it opaque. The read laser in a CD player senses the difference between clear dye and opaque dye.
