What does 52X ,36X ,45X stands for in CD or DVD?

Question

Does it stand for speed of reading or writing? What is the exact technology behind the working of DVD/HDDVD/ Audio CD,Video CD's and how could i copy Mp3 songs on CD having good quality?I copied Mp3 songs with usual burning data on CD but the quality of songs is not good.Where can i get detailed information regarding it?

Answer 1

Yeah, its how many bytes of information it writes per second.

Answer 2

The number before the X could be either reading or writing, although I expect that the speeds that you give there are reading speeds.

Explaining the exact technology behind the CDs would take me way too long... try doing an internet search or something.

As for copying MP3s onto CD, MP3 files, by nature, produce lower sound quality than standard CD audio files. There is no way to recover the lost information. What you would have to do is use MP3s with a higher bit rate or copy the original CD tracks directly.

Hope this helps.

Answer 3

It represents maximum reading speed.

CD 1x = 0.15 MBytes/second and DVD 1x = approximately 1.38 MBytes/second (some say 1.35).

Speed can vary over the surface of the disc with more data per revolution at the outer edge. Example speeds on reading 1 GB video files on a 16x DVD were 10.6 to 16.6 MB/second, compared with max spec of 22 MB/sec.

I know little about MP3 except that it is digital and compressed and files encoded with a lower bit rate (for smaller size) will generally play back at a lower quality.

Answer 4

Max recording speed.

Answer 5

Errr............Speed......... Please fill in the form below explaining just how long you have been on this planet and how long you are going to stay.
