Glossary
CAV disc
The Constant Angular Velocity (CAV) or standard-play disc
rotates at a constant 1800 rpm. Each track, or the path
traced by the laser for a single rotation of the disc,
produces a single frame. Each side of the disc holds up to
54,000 frames, the equivalent of 30 minutes of playback.
Each frame has a number that is stored with the data on
the disc.
CUV disc
The Constant Linear Velocity (CLV) or extended-play disc
doubles the maximum playing time to 60 minutes by
varying the rotational speed from a maximum of 1800 rpm
to a minimum of 600 rpm as the laser beam moves away
from the center of the disc. The disc surface therefore
moves past the laser head at a constant rate, and each
track is longer than its predecessor.
Digital sound disc
Some LDs include a high-quality digital audio signal as well
as a more conventional analog signal. This unit reproduces
both signals with priority placed on the digital audio signal.
Chapter number
Some discs are divided into sections, called chapters. Such
discs usually have a list of chapters on the jacket or label.
Each chapter is numbered for easy location with the
chapter search function, or for use with the repeat and
program functions.
Frame number
The frames on standard-play (CAV) discs are sequentially
numbered for rapid access with the frame search function.
Time number
Extended-play (CLV) discs calculate position in terms of
playing time from the start of the disc. The time search
function provides rapid access to desired scenes.
Track number
CD and CDV discs assign track numbers to each selection.
Rapid access to desired tracks is possible with the track
search function. Track numbers are also used with repeat
and program functions.

(Table of Contents) signals recorded. When playing back
LDs with TOC signals, the additional features given below
can be enjoyed.
