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.

CRW-3212A specifications

The Asus CRW-3212A is an internal CD-RW (Compact Disc-ReWritable) drive that entered the market during the early 2000s, addressing the growing need for optical storage solutions. Known for its impressive performance, this drive became an essential component for users looking to write and duplicate CDs efficiently.

One of the standout features of the CRW-3212A is its writing capability. It supports a maximum write speed of 32x for CD-R discs and 12x for CD-RW media. This swift writing capability was particularly appealing for those who frequently burned data, music, and video onto CDs, allowing users to create discs in a matter of minutes. Additionally, the drive offers reliable read speeds of up to 48x, ensuring rapid data access and retrieval.

The drive boasts Buffer Under Run technology, a significant innovation that alleviates the risk of incomplete burns. Buffer Under Run errors occur when the data flow to the drive is interrupted, potentially compromising the quality of a disc. With this technology, the Asus CRW-3212A can temporarily pause the writing process while the buffer is refilled, minimizing the chances of errors and ensuring smooth and successful burn sessions.

Another notable feature includes its compatibility with various CD formats, such as CD-R, CD-RW, and CD-DA. This versatility allows users to not only burn data but also create audio CDs for personal use or distribution. The drive's support for different CD formats makes it an ideal choice for a wide audience, from casual users to professionals in need of reliable media creation tools.

In addition to its performance features, the Asus CRW-3212A was designed with user convenience in mind. It comes equipped with an IDE interface, which makes it easy to install in desktop systems. The drive also includes software support for mastering and burning tasks, further enhancing the user experience.

Overall, the Asus CRW-3212A stands out as a robust optical drive that combines high writing speeds with advanced technologies to provide reliable CD writing and reading capabilities. Its legacy in the optical storage space highlights the importance of versatile and efficient solutions for data storage during a time when CDs were a primary format for data transfer and media consumption.
