CLV

C onstant L inear V elocity playback in magnetic and laser discs where the disc rotates at varying speeds. Relative to CAV constant speeds, the CAV approach results in constant data retrieval times that do not depend upon where the read/write head is located relative to the disc spindle. CLV videodiscs hold up to 60 minutes of video per side of a 12-inch disc. However, CLV discs cannot be searched for individual frames as effectively as CAV discs. (See also CAV )
