![]() As expected, the more versatile CDRW disc is pricier than a CDRW disc. Lastly, the cost of the two medium are not the same. Newer models can read both CDR and CDRW, but for those with older hardware, a CDR is the safer bet. Because of the difference in material with the CDRW, some older drives and players, like discmans and stereos, may fail to recognize and read the data stored in a CDRW. The main advantage of the CDR is compatibility with older CD-ROMS. A CDRW requires a better laser though compared to a CDR. The state of the metallic material can be changed while that of the dye, once activated, can no longer be changed back. This increases the usable lifetime of the disc extensively as you can keep reusing the disc.ĬDRW achieves this by using certain metals to store the data rather than dye, like with CDRs. ![]() This means, that you can erase the information stored on it and write new data whenever you want. Once it is full, you can only read data from it. ![]() The main difference between these two is reusability as a CDR can only be written to once, although you don’t have to write to the entire disc at once. At first glance, you’d be hard pressed to identify one from the other without the distinctive writing on the top side. CDRW and CDRW are two compact discs that allow the user to store information on them. ![]()
