The same only happens with the burner of DVD that in this case are DVD-R. In addition we can to find another category the regrabables CD and dvd. Unlike the CD-R, discs CD-RW yes can be erased, or even formatted (it allows to use the disc, losing a part of his capacity, but allowing to record in the new files). In the case of using a CD-RW when we erased we erased, it completely, are possible also to be made erasures partial, that need a greater power the laser to return to record itself. A disc CD-RW can be used like a diskette, with suitable software, whenever the unit has supported this characteristic, can be manipulated files like in a diskette, with the reservation of which not flock, but when erasing a file this continues occupying a space in the disc, although when examining it does not appear it this file. Discs CD-RW need more power the laser to be able to record itself, the regrabables discs therefore have a speed of recording smaller than taxable discs (they take more in finishing recording itself). Cleaning and virgin storage of the CD and the virgin DVD So that the disc stores all the data in form complete and by very long time, it is necessary to conserve the correct disc in the packings or places.
The part reflectivas of the disc must be clean and free of rayaduras, to avoid the loss of data. He is recommendable to transfer the data of an old or eroded disc, to another clean or new disc, before all the data are lost with time. It is only recommended to clean the disc if he is very dirty and appear jumps of image and/or sound, or read errors. Since the systems of correction of errors can read the data through a moderate amount of scratches and/or tracks.
