Need for burning of disk at home You may need to create the copy of audio disk or DVD for use in case you lose the disk or it is damaged unintentionally by someone. The time and money required for getting a new disk will be reduced if you have a back up disk. You may also save some important data by making a back up copy. Doing it in the privacy of your home ensures security. DVD Burning process The DVD writer has become the norm in many computers available today even in less developed countries. There are many manufacturers of DVD writers today and the DVD writers are capable of writing CD-Rom, Audio CD, Mixed mode CD containing data and music and pictures, video CD, Super video CD, and DVDs. Most of the DVD writers come bundled with the required software for writing to DVD and making copies of CD or DVD. A CD or DVD has a layer of an organic dye layer or crystalline metal alloy in the recording layer of the disc. This layer is heated by the laser in the writing head of the disk. The recorder records the information by selectively heating the organic dye layer in the disk. The change in the reflectivity of the dye due to this heating encodes the information so that it can be read by the by the reading laser beam. Difference in the CD/DVD ROM and DVD-RW The change in the recording layer will be permanent as in the CD-ROM or DVD ROMs. For the DVD+RW the change will be in the crystalline metal alloy layer. The subsequent re-recording will re-melt the crystalline metal alloy to the required level and the process can be repeated nearly 1000 times. What DVD burning software does? The software for this purpose changes the laser beam strength and makes sure that the process is controlled as per the requirement of the work being done on the disk. Typical DVD Burning Software Choices In typical DVD recording software, you will find the following modes for writing to the disk. 1. CD ROM
2. Audio CD
3. Mixed mode CD
4. CD extra for data pictures and songs
5. CD copy
6. video CD burning
7. Super video CD burning for burning MPEG-2 files
8. CD ROM boot for your operating system
9. DVD with MPEG-4 format
You may need to select the various modes for writing to the disk that you are going to make. Make sure that you have all the required settings before you burn the disk otherwise the entire disk may go waste if you are not careful. How does the software work? The software first makes an image of the file system to be recorded and then starts the process of burning on the disk. Any interruption in this process is the end of session. Earlier only single session could be managed and the disk space could not be written later as the lead out from the disk was completed in one session. Multi Session Disks Software Later, multi session disks were developed and this made the process continuous from one session to another. In the multi session recording you will be given option of closing the entire disk at the end of this session. This will either close the recording or keep it open for the next step. During Burning Process The burning process does not require and intervention of the person recording the disk. Any ejection of disk may change the recording parameters and make the disk suitable for use as coaster of tea cup. Therefore, do not do anything unless software gives you the message that the recording was done successfully. |
