A method that allows 23 Gbytes of multimedia data to be written to a single 30-cm disc.

Constant-Minimum Wavelength-Constant Angular Velocity is the name of a technology developed by NEC Corp. in Japan in the 90s.  CWL-CAV allows 23 Gbytes of multimedia data to be written to a single 30-cm disc. 32 minutes of NTSC composite digital signals can be recorded without compression. Using MPEG-2 compression at 8 Mbits/s, up to 5 h of full-motion video can be recorded on a disc.
