Essentials Of CDR

The simple rule of thumb is that whatever you have

stored as a file on any other storage medium can

also be stored as a file on a CD-ROM. To the

recorder, a file is a file, and an ISO doesn’t

care whether or not the file contains pictures, text,

or even audio sound.

There are a few special cases, as to where you

would want to record a file to a CD in a special

type of format. The most obvious here is CD-DA

audio. If you wanted to record an audio file to

a CD so that you could play it back on your home

stereo, you would need to write a CD-DA (or Digital

Audio) disk.

When you copy data to a CD, you need to ensure that

your data doesn’t exceed the capacity of the CD

that you will be recording to. Due to the audio

requirements of CDs, the amount of information a

CD can hold is measured in minutes/seconds/sectors.

Each second can contain 75 sectors, each of which

are capable of holding 2,048 bytes of Mode 1 user

data.

By using the CD Size command in the edit menu, you

can set the capacity of the set you wish to

produce, which will help you to prevent exceeding

it. The status bar will show you how much space

you have used, how much remains free, and the

percentage of each one.

Even though this may sound a bit confusing at

first, keep in mind that it may take some time if

you are new to computers. Even though copying a

CD is quite easy, knowing the limits and how things

work is a bit more complex. Give it some time,

and you’ll be copying files to CD like the pros

do it.
