Zone CLV Recording Method
Zone CLV Recording Technology
The Zone Constant Linear Velocity (CLV) recording method allows you to
achieve a higher recording speed by using a different speed for each of
the four zones partitioned from the inner to the outer area in a disc.
When using the Zone CLV, the recording speed in Zone 1 is 16X, then
increases to 20X speed in Zone 2, after t1 time. In Zone 3, the recording
reaches 24X speed after t2 time. In Zone 4, the recording speed reaches
32X after t3. The maximum recording speed of 40X is attained in Zone 4
after t4 time.
