Topic: How come CDs hold 700MB OR 80 minutes of audio?

80 minutes of audio is around 800MB. The RIFF Wave header can't take up that much space, right?

A CD can hold 74 minutes of audio, and that's because a major contributor to the development the CD, Norio Ohga, was a huge fan of Beethoven's 9th Symphony in D minor, which is 74 minutes long.

And then things improved and the limit was expanded to 80 minutes.

CDs are unserious fraud technology.

And yet DVD, BluRay, and the now defunct HD-DVD are all based on CD.

@OP
Did some research and found that CDs do in fact contain more than 700MB of data. When you write to a CD as a data CD, some of the memory is redundant for the purpose of error correcting, so only 700MB is really usable. Music CDs do not use this redundancy and therefore have more space to work with.
