A CD can hold approximately 75 minutes of music (on one side).
HP has a CD-ROM product which claims to hold "over 550 megabytes" on a
"three-mile long spiral track with a density of 16,000 tracks per inch".
The pictures in the brochure definitely show labeling on one side of the disc,
so I assume that only one side is being used for data.
