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.
