ilitws Posted June 5, 2010 Posted June 5, 2010 Background Happy, grateful, loyal user of ImgBurn 2.5.1 Concept Understood So Far DVD/HD DVD/BD only supports one track mode - Mode 1. This is regardless of whether you burn via Build mode (mp3 files, avi files, doc files, xls files, jpg file etc) all end up in a data track. Clarification Kindly Required CD supports Mode 1, Mode 2 and CD-DA How does CD Mode 1 differ from CD Mode 2 differ from CD-DA i.e. when does each one of them get used?
LIGHTNING UK! Posted June 12, 2010 Posted June 12, 2010 Read the MMC specs or use Google. We're not wikipedia!
ilitws Posted June 18, 2010 Author Posted June 18, 2010 I did that. I've tried my best. This is how I understand when to use which mode while writing CD in ImgBurn 2.5.1. Have I understood it correctly? 1) The user needs to decide which of the 4 modes is best suited to the task. Fundamentally it is the drive i.e. firmware which supports or not supports the 4 various CD writing modes. If you have the appropriate firmware (not merely the latest update of the given firmware) it would allow you to choose any one of these 4 modes. If you do not have the appropriate firmware then you would not be allowed to use some of these modes. The 4 CD writing modes are :- 1) CDDA 2) Mode 1 2) Mode 2 Form 1 3) Mode 2 Form 2 XA 2) CDDA - can be used for digital audio CD's. It is specially made for that purpose 3) Mode 1 - Can be used for any data (multimedia file or non multimedia file) only if you do not want to write multimedia files & non-multimedia files to the same CD. Can be used only if the media is not VCD or SVCD. VCD & SVCD standards do not allow Mode 1 form of CD writing. Since Mode 1 allows error correction (there is less chance of data getting corrupted). It has set aside certain number of bytes of code for error correction. As a result of this you can save less data than would have been the case had a portion of code not been set aside for error correction. So as a user you need to decide whether it is worthwhile to gain the benefit of error correction by foregoing being able to save more data. You may need to sacrifice upto 12% space in order to gain the benefit of error correction. 4) Mode 2 Form 1 - Can be used for any data (multimedia file or non multimedia file) if you do not mind writing multimedia files & non-multimedia files to the same CD. Can be used even if the media is a VCD or SVCD. VCD & SVCD standards allow Mode 2 Form 1 method of CD writing. Since it allows error correction (there is less chance of data getting corrupted) it has set aside certain number of bytes of code for this purpose. As a result of this you can save less data than would have been the case had a portion of code not been set aside for error correction. So as a user you need to decide whether it is worthwhile to gain the benefit of error correction by foregoing being able to save more data. You may need to sacrifice upto 12% space in order to gain the benefit of error correction. Your drive i.e. firmware if it allows Mode 2 Form 1 operates upon what is called XA (Extended Architecture). One need not bother understanding what XA means. 5) Mode 2 Form 2 XA - Can be used for any data (multimedia file or non multimedia file) if you do not mind writing multimedia files & non-multimedia files to the same CD. Can be used even if the media is a VCD or SVCD. VCD & SVCD standards allow Mode 2 form 2 XA method of CD writing. Since it does not allow error correction you can save more data than would have been the case had a portion of code been set aside for error correction. So as a user you need to decide whether it is worthwhile to forego the benefit of error correction for the sake of being able to save more data. You may be able to save 12% more data in terms of file size. Your drive i.e. firmware if it allows Mode 2 Form 2 XA operates upon what is called XA (Extended Architecture). One need not bother understanding what XA means. So as a user one has to choose the CD writing mode which suits the task best. I have only one request. Have I understood the matter correctly? I'd be grateful if you could let me know.
