The high density of tracks and smaller size of the pits and bumps is the main reason. In order to transmit the amount of data contained on a DVD, a more advanced means of transport would be necessary.
While the laser in an ordinary CD-ROM drive has a nanometer nm wavelength, DVD drives use lasers with nm or nm wavelengths, thereby supporting more than double the pits per track, and more than double the tracks per recording surface.
Analysts predict that it will be late before 4. This paper will deal with contacting people at a variety of organizations for information, but we will not be working directly with anyone.
Also, the typical high-end usage of notebooks is for corporate presentations which are often multimedia demanding. As previously stated, DVD provides higher quality picture and sound than VHS tapes, yet can be purchased for about the same cost. By making the first layer semi-transparent, a second laser could actually punch through and read the data on the layer beneath.
Thus a long spiral of data can be created which is together called a track. What this implies is that the more advanced means of transporting data over networks will need to be made available to the general population, whereas they are only available in some areas at the moment.
Re-recordable media which are small in physical size and weight, yet large on capacity, are ideal for the notebook user. The price of DVD is comparable to many videotapes and less expensive than laser discs. DVD can use subtitles in almost 32 languages with a soundtrack in 8 languages.
The DVD has a number of layers of plastic pieces with a total thickness of 1.
