How much music or data will fit on a standard CD?
Standard CD – A round disc with a 120mm diameter and a capacity of 650 to 700 megabytes. That means approximately 74 to 80 minutes of audio or the data equivalent. It can be read on any standard computer’s CD-ROM drive and is compatible with most up to date CD players. The discs we use have a maximum capacity of 700MB or about 80 minutes of music. Some of this space is used up with space between audio tracks on audio CDs or indexing information on data CDs. To add up the total time of your audio tracks, add the time of all the individual tacks together and then add 2 seconds at the beginning of the disc and 2 seconds between each track, if you choose to do so, to your total. For data CDs, a general rule of thumb is to allow about 10 to 15 MB of space for indexing. So the maximum total size for files on our data discs is about 685 MB. In the event that the source files you submit to us do not fit on a disc, we will contact you.
