Detailed explanation-1: -The circular shaped material that stores data up to 700 Mb is known as an optical disc.
Detailed explanation-2: -Standard CDs have a diameter of 120 millimetres (4.7 in) and are designed to hold up to 74 minutes of uncompressed stereo digital audio or about 650 MiB of data. Capacity is routinely extended to 80 minutes and 700 MiB by arranging data more closely on the same-sized disc.
Detailed explanation-3: -Their main reason for doing this was to allow the continued production of 700 MB disk for the already existing base of CD players. The next time they upgraded the storage on the CD (or DVD) it became the BlueRay disk. So there are “CD-ROM” disk that hold more than 700 MB.
