Features
The ASUS CRW-4816A is a CD-RW drive with 48X-write, 16X-rewrite, and 48X-read capabilities. The drive complies with the AT Attachment Packet Interface (ATAPI) specification and comes equipped with the latest innovative technologies in CD recording. Highlighting the major characteristic of ASUS CD-RW drives, the CRW-4816A strategically identifies the media quality at the beginning of the recording so that it can apply the appropriate writing speeds and ensure effective data storage. Thanks to the FlextraSpeedTM and FlextraLinkTM technologies developed by ASUS. FlextraSpeedTM increases accuracy and reliability when rewriting across a broad base of certified media, while FlextraLinkTM prevents buffer underrrun problems to eliminate the creation of unusable discs. The following sub-sections describe these technologies in detail.
FlextraSpeedTM Technology
The ASUS FlextraSpeedTM technology provides the optimum solution to ensure quality recording when using discs that require flexible speeds. The CRW-4816A drive employs this technology that allows automatic recording speed adjustment based on the recording media. The DDSS CD-ROM technology is designed to reduce the vibration generated from spindle rotation of over 8900 rpm of 40X CD-ROM drives. 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.

Partial Constant Angular Velocity (P-CAV) Recording Technology
The Partial Constant Angular Velocity (P-CAV) recording method is a combination of the Constant Angular Velocity (CAV) and Constant Linear Velocity (CLV) recording technologies. In CAV recording technology, the drive maintains a consistent rotation speed which will result in a variable transfer rate, while in CLV recording technology, the data transfer rate is kept at a fixed level by changing the rotation speed. P-CAV recording technology switches from CAV to CLV once the maximum transfer rate is reached. Unlike Zone Constant Linear Velocity (Z-CLV) recording, no links are produced in the P-CAV recording process, resulting in a higher average transfer rate. The following illustration compares the Partial Constant Angular Velocity (P-CAV) and Zone Constant Linear Velocity (Z-CLV) recording technologies.

1. [. . . ] If your computer has a sound card or an onboard audio feature, connect an audio interface cable to the 4-pin analog audio connector on the rear of the drive. Connect the other end of the audio cable to the connector on the sound card or on the 4-pin CD connector on the motherboard. All the cable plugs are slotted so that they fit in only one orientation. If a plug does not fit in completely, try reversing it. [. . . ]
