What is the storage of a DVD?
A standard single-sided, one-layer DVD can hold 4.7 gigabytes of data and 8.5 GB if it's a double-layer disc. A single-layer HD-DVD stores up to 15 GB of storage capacity, and a dual-layer disk provides up to 30 GB.
What is the storage capacity for CD?
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.
Why is the capacity of DVD more than a CD?
Less Overhead, More Area
The DVD format doesn't waste as much space on error correction, enabling it to store much more real information. Another way that DVDs achieve higher capacity is by encoding data onto a slightly larger area of the disc than is done on a CD.
