The drive complies with the Universal Serial Bus 2. 0 (USB 2. 0) specifications and comes equipped with the latest innovative technologies in CD recording. ASUS External CD-RW drives are accentuated by the latest innovations in CD-recording technology, namely: FlextraSpeedTM, FlextraLinkTM, DDSS II (Double Dynamic Suspension System II) and the Constant Angular Velocity (CAV) recording method. The diagram below shows the advantage of the FlextraLinkTM recording technology. FlextraLinkTM Technology Solution Data Data Data transfer slows down Buffer Memory Buffer Memory Empty Conventional Recording Write Data Data transfer slower than write process Data Write process continues Bad disc results Write Data Buffer Memory Data Data transfer slows down Buffer Memory Data Data transfer continues and fills buffer with sufficient data for writing Buffer Memory Recording with FlextraLinkTM Technology Write Data Write Data Write process stops; waits until there is enough data for writing Write process continues until writing is complete ASUS CRW-5224A-U User's Manual 11 Double Dynamic Suspension System (DDSS II) The DDSS II is an enhanced follow-up to the DDSS anti-vibration system developed by ASUS. 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. DDSS / DDSS II Design Structure 12 ASUS CRW-5224A-U User's Manual Constant Angular Velocity (CAV) Recording Technology The CRW-5224A-U 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. This is primarily advantageous for computer applications.
