Part 1. What is Blu-ray?

Actually, Blu-ray is a new optical high definition disc format which is developed by a group of media manufactures in 2006. Blu-ray is also called Blu-ray Disc which is commonly known as BD. Compared with current optical disc technologies such as DVD, DVD-RAM which all use a red laser to read and write data, Blu-ray relies on a blue-violet laser which has a shorter wave length. This feature could enable the disc to pack data more tightly in less space. So Blu-ray could provide consumers an unprecedented HD experience with the extra capacity combined with advanced video and audio codecs. In comparison with DVD, Blu-ray could provide a better picture and higher definition.

Since many people adopts Blu-ray disc as the storage medium, it is quite important to know on how much data can a Blu-ray disc hold. Why does the Blu-ray disc hold such a large quantity of data compared to common DVD disc?

The pits and lands on a Blu-ray disc are packed together at a microscopic level so that it can store much data.

So how much data can a Blu-ray disc hold anyway? In fact, there are two types of Blu-ray discs: single-layer disc and dual-layer disc. For a single-layer disc, it can hold up to 25GB data. But some of the space is reserved for the file system which occupied about 1.7GB data. Therefore, a single-layer Blu-ray disc can hold up to 23.28GB data. As the same rule, the dual-layer Blu-ray disc is normally rated with 50GB capacity while the dual-layer Blu-ray disc's true data capacity is 46.57GB besides from file system reserved space. Someone has already predicted that in the future the storage capacity of Blu-ray disc will increase to 100GB-200GB by adding more layers to the disc.
