DVD is slowly gaining ground

More and more dealers are installing DVD drives in their computers instead of CD. This is nothing new, because the first DVD drives have been available since 1997, but now almost every major retailer such as Saturn or Media Markt offers a DVD drive to go with the cheap PC.

Technically speaking, the DVD is a further development of the CD-ROM. Up to 17 GB can be stored on the DVD. So that the higher storage capacity can be realized, the data data packets are written more densely than on a CD, i.e. the distance between the 'pits', the small recesses in the DVD/CD, is smaller. Unlike in a normal CD drive, the laser in a DVD drive is a red-light laser whose wavelength is shorter. However, it is still possible to read standard CD-ROMs and audio CDs, only CD-Rs and CD-RWs could cause problems with older DVD drives. Due to their large storage capacity, DVDs are particularly suitable for feature films. These can often be heard in several languages ​​and different sound standards (e.g. AC-3, stereo, etc.). The price for DVD drives (approx. 400 DM) is very cheap in contrast to stand-alone devices (approx. 600 DM), since you can not only read data DVDs with DVD-LWs, but also as stand-alone Devices can also play videos. But this advantage can only be used if you have a computer of the new generation, which is accordingly fast. Older computers need a decoder card for video fun.
