When i write a CD it is asking for the speed such as 18x,42x?Why?

Question

what is use of that option?Suppose if i write a CD with 52x speed will it read the contents at that speed or it is Hardware Dependent?

Answer 1

It asks cause your CD writer supports writing at these sppeds. The faster you write, quickly the CD will be written. But sometimes CDs go useless if we write at very high speeds and the burning process fails. So write at moderate speeds.
Your drive will read the data regardless of the speed at which you burnt the CD. The reading is always a different specification and your drive will read all the CDs at the same speed, if there is nothing wrong with the CD itself.

Answer 2

Depending on the type of media (CD brand), burning it at a high speed will sometimes make unreliable Cd's. If you slow down the burner, it will make the indentations on the CD-r a little better and will give you a more reliable disk. If I make a CD for someone, I burn it at the max speed, if I make one for myself, I use the slowest speed. This is just a theory of mine, but I have seen a difference in quality depending on speed. And to answer the last part of your question: No. If you burn a CD at 52x it will not necessarily be read at that speed. Like you said, it is hardware dependent, so it'll be read at the CD-Roms speed limitations.

Answer 3

This is the speed at which the system writes the data on the CD. 1X = 150KB/s.

Its a better option to write CDs at a max of 24x. If you write CDs at 52x they never get write at that speed bcoz it require very high quality disk not the local ones. And also your system should be enough powerful. And there is only max of 2 min difference in time if you write at 24x and 52x but at 24x the disk rotates at much lesser speed and that gurante a better quality writing.
