Unprecedented, Fast DVD Recording Speed
With BenQ DW1620, recording a full 4.7GB DVD+R disc takes only 6 minutes at 16x!! The BenQ DW1620 also brings you the fastest DVD-R recording speed at 16x, which allows you to record a full 4.7GB DVD-R disc in 6 minutes.

Double Layer Recordable DVD
Experience the greater data storage capacity of 8.5GB using DVD+R DL discs !! You can record up to 16 hours of VHS quality video, or 4 hours of DVD quality video on a single disc, while retaining disc compatibility with DVD video players and DVD-ROM drives.

Write Right Technologies
As writing speed is increased, signal loss becomes the key cause of a Significant decrease in writing quality. BenQ's High-Speed Signal Algorithm manages the high EFM(Eight-to-Fourteen Modulation) frequency signal loss that often takes place at high-speed writing - ensuring superb writing quality.

WOPC + BLER OPC
Unlike other drives which preset the writing power before the actual writing of data, the WOPC II (Walking Optimal Power Control) algorithm evaluates the writing quality constantly and adjusts the writing power accordingly in order to ensure the best possible writing quality over the entire disc. The BLER OPC (Block Error Rate Optimal Power Control) further enhances the writing quality near the end of the disc, where the risk of warping is higher.

Tilt Control
Optimal reading and writing quality is obtained when the angle between the disc and the laser beam is 90 degrees. However, if a disc is warped, the laser beam many no longer be correctly positioned. BenQ's Tilt Control repositions the OPU (Optical Pickup Unit) to maintain the 90-degree angle between the disc and the laser beam in order to ensure the best writing quality.

Sliding Cone Mechanism
With the unique Sliding Cone design, the disc position on the turntable is improved considerably. This greatly helps to reduce data access time and also to deliver superior reading and writing quality.
