Capacity


A CD usually has 650Mb organized into 335250 sectors of 2 kb each. This is equivalent to 74 minutes of high-quality sound. A CD can hold a minimum of 650 Mb but capacity depends on several factors such as rotation velocity or the pitch of the track. It is sometimes possible to record or copy more data that the nominal capacity (over writting) but some readers will have problems reading it.
