Some of the original specifications are for audio playback, like a requirement for 90 seconds of silence so a machine could tell when the CD was finished playing.

Some software and drives can write data to these areas, called overburn. Data on a CD is stored as a continuous spiral of dots and dashes.

To guide the laser while burning to a writeable disc, the plastic is molded with a spiral called the pre-groove. If you tighten the curve of the spiral, you can actually fit more data onto the disc, as long as your machine is capable of following the tighter groove. Problem 2 CD was created as an audio format. What about 34, 90 and 99 minute CD-R discs?

To achieve these higher capacities such discs do not conform to Orange Book specifications and, as a result, may not write in all recorders, be accessible to all software or readable in all players and drives. Using 34, 90 and 99 minute CD-R discs is therefore not recommended. For any given data format disc capacity can be calculated by multiplying the appropriate user data area size by the CD data transfer rate of 75 blocks per second by 60 seconds by the minute size of disc.

It should be noted, however, that in the real world capacity can vary slightly among discs from different media manufacturers. For discs written with computer data the logical format used also consumes space available for user information.

For example, the overhead for the first session of a multisession disc consumes 22 MB of space and each subsequent session thereafter uses 13 MB. What is the difference between 74 and 80 minute discs?
