Finally tax name y burning rate disk as a name you can choose what you want, in terms of writing speed, I recommend keeping it medium-low and press the button again siguiente , to start writing data. For more details on what to do, see my guide on how to burn a CD.
You are right! The famous multimedia player of the OS Microsoft also allows you to perform this type of operation. How I will explain it right away. First, insert the floppy disk on which you are going to act in the burner connected to the PC, ignore any message related to the autorun and start the Windows Media Player, remember it from the Start Menu or selecting the relative link present on the desktop.
If you can't find Windows media Player on your Pc, you can easily fix it by reading my tutorial on how download Windows Media Player. Now that you see the WMP window on the screen, identify it in the left sidebar recorder input containing the CD or DVD of your interest, right click on it and select the option Delete disk from the context menu. Then confirm your willingness to format the disk by clicking the button yes in the additional window that is displayed. When formatting is complete, to be able to burn the disc with Windows Media Player again, thus obtaining a audio disc or data disc , select the card burn located in the upper right, click on the button Recording options Located at the top right and choose the type of disc to record from the menu that opens.
Later, if you choose to create an audio disc, select the item music from the left sidebar and drag tracks to record in the right pane of the program. If, on the other hand, you have chosen to burn a data disc, in addition to the section music you can explore those too video y photos , which you can always find in the left sidebar, and drag items of your interest from there to the right side of the Windows Media Player screen.
Finally, start writing the disc by clicking on the item Start burning appeared in the upper right corner and waits for the procedure to complete. For more information and other customizations to write the disc, I refer you to read my guide specifically focused on burning a CD with Windows Media Player.
Unfortunately it is not free it costs Note that the program can also be used in two other variants, the Platinum Suite and Standard suite , also paid and includes advanced functions and tools.
That said, to download Nero Burning ROM on your PC, connect to the latter's official website and click on the button Download placed next to name of the program. Then write yours email in the appropriate field and click on the button Download it now. For more information on downloading Nero, you can read my guide specifically dedicated to the topic.
When the download is complete, open the archive. Then press the button Launch Nero to start the program and insert the CD you want to rewrite in the recorder connected to the PC. Now that you see the software window on the screen, click the button Nero Burning ROM and select the item Erase rewritable disc of menu burner located at the top. In the window that opens, select the CD drive to delete, indicates the cancellation mode that will be carried out Quick erase of rewritable disc to delete files quickly but superficially or Full erase of rewritable disc to format the CD content in a slower but more advanced way , leave the erase speed on MAX and click on the button clear , to complete the procedure.
These spots can then be erased in a process known as annealing. This is accomplished by heating the material to a lower temperature, which transforms it back to its crystalline state. Existing data can be overwritten by turning the laser on continuously to the erase power, which will erase any existing marks. Switching the laser to a higher power, one sufficient to melt the material, enables the creation of a new mark. Once an area of the disc has been written to, it cannot be erased.
The recordable layer is an organic cyanine or pthalocyanine dye. Initially, the organic dye has high reflectivity. When the laser is applied in write mode, however, a chemical reaction occurs that makes that "pit" less reflective than the "land" around it. During readout, the laser detects the difference in reflectivity between the "pits" and "lands" to read the data or music. CD-R discs are highly reflective--about 60 to 70 percent of light is reflected or bounced back to the photo detector or read laser.
Phase change technology enables this rewriteability. The recordable layer on a CD-RW disc is made up of a rare-earth metal alloy "sandwich," which includes silver, indium antimony and tellurium elements. This combination of elements has an important property: it allows a spot on the disc to be changed by the heat of a laser from a crystalline state high reflectivity to an amorphous state low reflectivity.
Heated to a lower temperature or power level, the same spot changes back to crystalline state. When overwriting data, the laser is modulated first to erase or make crystalline the spot to be recorded and then modulated to write power. Phase change technology does have a limitation: it has very low reflectivity approximately 25 percent. Answer originally posted September 10, Sign up for our email newsletter.

Or is there a more technical reason, ie. CDs store their data magnetically correct? Sorry if that's completely wrong; I have no idea how CDs work. Data on a regular CD is stored by making pits holes , or not-holes lands , on the CD medium.
The pits disturb the reflection of light. Transition from a 0 to a 1 or vice versa is determined by the start or end of a pit this is called NRZI encoding. There is further complication as these bits are the "channel code", not the content bits; the latter are recovered by decoding the former. And then some of the "content" bits are really Error Correction Code bits. But ultimately, the bits are encoded via holes or not-holes in a reflective layer of metal, usually aluminum.
A CD-R works somewhat the same. It has a reflective surface, but this surface is covered by a dye. Light is either reflected or not. Note: Rewriting with the same image or a image with only the right bit changed would seem to be technically possible, but there are limits as to what could be done.
The best you could do would be to burn a "pit" in the middle of a long "land". Since lands have a maximum length of ten bit-times, and both pits and lands have a minimum length of three, this would only be possible where an existing land was nine or ten bits long, and the only possibility would be a pit three or four bits long.
Doing this would add two bit flips, and this in turn would necessitate changing ECC bits at other places in the same block. The chances that every such change could be done by adding a pit in the middle of a land are very, very small, even if there was software or drive firmware that would allow the attempt. The disc comes out of the box reflective, but then your drive burns the solid thin chemical dye layer below the plastic and "roughens" it so it becomes slightly transparent.
This makes the light disperse when a laser hits it, thus it counts as a zero essentially since the laser gets little light back. There is no way to fix this burned area and make it reflective again. The only way to wipe the data, is to turn into Asus makes software called E-Hammer that may work with non-Asus drives:. Once the data is deleted, it cannot be recovered or restored, and the optical drive will not be able to read the disc. This ensures data security, eliminates the hassle of scratching your old discs, and conforms with our commitment to environmental protection.
If there were software that would just make the laser burn 0's across the disk and ignore the formatting and toc etc. DD in Linux can probably do it.
