What Is a Digital Versatile Disc?

Digital versatile disc (Digital versatile disc). This kind of disc is different from the previous disc media. It has a thin disc, which can be bonded by two 0.6mm discs. The capacity can reach 9.4GB or even higher. Therefore, the image has high definition and high fidelity. Using a shorter wavelength red laser, a more efficient modulation method and a stronger error correction method can support a double-sided structure. DVD will become a popular next-generation optical disc and a replacement for CD-ROM.

Using a shorter wavelength red laser, a more efficient modulation method and a stronger error correction method can support a double-sided structure. DVD will become a popular next-generation optical disc and a replacement for CD-ROM. ^[1]

Lossless link Digital versatile disc Lossless link technology

When burning, if you encounter system problems such as buffer under run or vibration, the Lossless Link will be activated and temporarily stop burning. At the same time, record the breakpoints. When the data flow returns to normal, continue to the last recorded location to continue burning. The gap between the recording breakpoints is controlled within 1 micron, which is enough to ensure the recording quality.

DVDBuffer Underrun Digital Versatile Disc DVDBuffer Underrun Technology

Buffer Underrun's waste film termination recording technology can fully guarantee the recording quality of the disc. At the same time, the heat dissipation hole design can facilitate the discharge of hot air to avoid adverse effects on the machine or the disc due to the high internal working temperature of the machine. It not only stabilizes the operation of the disc, but also ensures good recording quality.

DVDTilt control Digital versatile disc DVDTilt control technology

Tilt control is called "laser intelligent guidance" technology, and its role is to adjust the laser read and write power by itself to ensure the consistency of the disc burning process. Ideally, the disc should be perpendicular to the spindle motor of the recorder at 90 degrees.

In the actual recording operation, due to the different materials and processes of the recording disc itself, the inclination angle of the recording disc from the inside to the outside will be different, which will cause the power of the laser to be transmitted to the disc surface to fluctuate. The recorder equipped with laser intelligent guidance technology can intelligently adjust the laser power according to the quality of the disc and the operating status, thereby ensuring the consistency of the entire recording process.

DVDDefect management Digital versatile disc DVDDefect management technology

Defect management is also called intelligent error correction system technology. Its role is to effectively detect the defective parts on the optical disc, and once they are found, they will be recorded. During the process of reading and burning the disc, the recorder automatically skips these recorded areas, thereby ensuring the quality of the disc reading and burning. In this way, even if consumers inadvertently use low-quality discs, there is no need to worry about not being able to read the disc or the poor recording effect.

Quick Background Formatting

This is a unique technology of DVD + RW burner. Compared with DVD-RW burner, it must format the entire disc before burning (20-30 minutes). DVD + RW burner can perform fast background formatting. Function, after the recording disc is placed in the recorder, the disc is quickly formatted in the background automatically. If you start the recording at the same time when you insert the disc, you do nt have to wait until the entire disc is formatted. Burn.

DVDMt.Rainier Digital Versatile Disc DVDMt. Rainier Technology

This technology has also been added to some CD-RWs. Mt. Rainier's function is to drag directly on the hard disk with the mouse, without the need for complicated software operations to achieve the purpose of burning, making the burning work the same as copying files on the hard disk. Simple and user-friendly. ^[3]
