Blank DVD Space Question ?

[hgtvg]

Hi Guys !

I bought a Sony DVD burner Sony DRU-500 A(X) and i am fully satisfied but i wanna know how much data can i fit on a DVD ?

I mean i read a tutorial of DVD-9 to DVD-5 saying that i should setup to 4.32 Gb but the Blank DVD-R that i got (OPTODISK) says that it can fit 4.7 Gb (ref # OR 470-000). So why do i need to setup InstantCopy to 4.32 Gb ?

Can somebody help me to understand this issue ?

Thank you very much !

4.7 gigaBITS = 4.38 gigaBYTES

Your computer works in BYTES.
Discs sold in BITS.

Why? Good question.

Why? For the same reason CRT monitors are often rated in Size and viewable size. Bigger number = more good. Who cares if they have meaning to the average user right?

4 700 000 000 bytes / 1024 = 4 589 843 Kb
4 589 843 Kb / 1024 = 4 482mb
4 482mb / 1024 = 4,377Gb

Same for HD.. they count by 1000 insted of 1024
