CAV+ CLV : The latest in CD-ROM Disc Rotation Method
Your new 16X CD-ROM drive utilizes a combination of Constant Angular Velocity (CAV) and Constant Linear
Velocity (CLV) disc rotation to achieve the ultimate performance. Previously, CD-ROM drives utilized only CLV
technology to rotate the disc which resulted in a constant data transfer rate by adjusting the CD-ROM's rotation.
In other words, the drive's motor would slow down to read data located on the outer tracks.
However, as transfer rates increased beyond 1.2 Mb/sec (8X), the motor rotation became so fast that it caused
too much vibration and noise. With a combination of CAV and CLV technology, LG Electronics is able to achieve
a maximum transfer rate of 2.4 Mb/sec (16X), speed up the access time to 100ms. At the same time, CAV+ CLV
technology causes considerably less noise and vibration than high speed CLV only CD-ROM drives.
