constant linear velocity


constant linear velocity
   Abbreviated CLV. A changing speed of rotation. CDROM disk drives use a CLV encoding scheme to make sure that the data density remains constant. Information on a compact disc is stored in a single, spiral track, divided into many equal-length segments.
   To read the data, the CD-ROM disk drive must increase the rotational speed as the read head gets closer to the center of the disc and decrease as the head moves back out.
