[. . . ] The DDSS II improves this feature by handling up to over 10, 000 rpm of the new 50X drives. In addition, the DDSS II stabilizes the pick-up head of the drive in both horizontal and vertical directions, making tracking and focusing even more precise. Like the DDSS, the DDSS II vibration absoption structure contains a "dynamic mass" that can absorb the vibration caused by high revolution of spindle motor. However, the DDSS II moves the dynamic mass to be suspended to the chassis, thus providing more stability and accuracy when accessing data from the disc. The following diagram illustrates the DDSS/DDSS II design structure. DDSS / DDSS II Design Structure 12 ASUS CRW-5232AS-U external CD-RW Constant Angular Velocity (CAV) recording The drive employs the Constant Angular Velocity (CAV) recording method. With CAV recording, the drive spindle motor rotates the disc at the same speed regardless of the radial position of the pickup head. This means that there is a higher transfer rate when writing data to the outer tracks of the disc than to the inner tracks, as the head traverses a longer linear path on the outer than the inner part of the disc. Although the transfer rates vary, and may not be at maximum, depending on the part of the disc being written to, the CAV method allows faster recording speed because the rotation speed does not have to change when the head writes data to different areas of the disc.
