Dvd Virgin Tool

The CD-ROM drive must be considered compulsory on any computer that is built today, because most of the software is distributed on CD-ROM. Currently, although they are still used, they are starting to fall into disuse since they began to be replaced by DVD drives. This is mainly due to the greater possibilities of information, since a DVD-ROM exceeds capacity to a CD-ROM. But who are the CDs and DVDs? A CD-ROM (stands for Compact Disc Read Only Memory, compact disk read only memory), is a compact disk used to store non-volatile information. The CD is a disc of plastic plane with digital information encoded in a spiral from the Center to the outer edge.A standard CD can hold 650 or 700 MB of data. The CD is popular for distribution of software, especially multimedia applications and large databases weighing only 30 grams.A DVD instead fall into two categories: single layer and double layer.The Virgin of single layer DVD can store up to 4.7 gigabytes, about twelve times more than a standard CD.The DVD uses a more efficient encoding method in physical layer: systems of detection and error correction used on the CD, as the CRC cyclic redundancy check. Now well computer users want to save their own information and there is where are born the Virgin CD DVD Virgenes.y performed by the corresponding recorders or burns, either CD or DVD.

A CD reader is an electronic device that allows the reading of these discs using a beam of lightning laser and the further processing of these in impulsoselectricos that the computer interprets. These discs are written by CD recorders on the CD – R (blank Cd) with the difference that does the opposite to the reader, i.e. transform electrical impulses into a laser beam that stored CD data binary in the form of wells and llanos-. The same goes for DVDs only burning which in this case are DVD-R. In addition the cd we can find another category and dvd rewritable.Unlike the CD-r, CD-RW discs may Yes be deleted, or even formatted (allows to use the disk, losing part of its capacity, but allowing recording in the new files).

In the case of using a CD-RW when we delete, delete it completely, can be also partial deletions, they need more laser power to re-record it. A CD-RW disc can be used as a floppy disk, with appropriate software, provided that the drive supports this feature, you can manipulate files on a floppy disk, with the caveat that is not erased, but that when you delete a file this continues to occupy a space on the disk, although considering it does not appear that file. CD-RW discs need more laser power to burn, for this reason the rewritable discs have a recording speed lower that recordable discs (take longer to finish recording it). Cleaning and storage of the virgins CDs and DVDs Virgin for the disk to store all data in its entirety and for a very long time, need store the disc in gaskets or correct locations.The reflective side of the disc must be clean and free of scratches, to avoid data loss.It is recommended to transfer data from an old or eroded record, to another disk clean or new, before lost all the data over time.He is only recommended to clean the disc if it is very dirty and hops of image and/or sound, or reading errors appear.Since error correction systems can read data through a moderate amount of scratches or fingerprints.
