Development


16/20

What changes and improvement have been made to the

inventation

Blue ray have a bigger storage capacity thannormal DVD. A single layer of Blue ray can holdabout 25GB of data while normal DVD only canhold 4.7GB of data in one layer.

If we use the same amount of storage capacity butthe video we can fit into the Blue ray and normalDVD is different. For example, if we use 50GB of

storage capacity of each type of disk, Blue rayneed to use 9-hours to fit in high-definition(HD) into

50GB while the normal DVD need about 23-hours tofit the standard definition(SD) into 50GB.

The Blue ray will not easily face jamming problemcompared to the normal DVD.


17/20

How might it be improved in the future

To ensure that the Blue-ray Disc format is

easily extendable (future-proof) it also

includes support for multi-layer discs, whichshould allow the storage capacity to be

increased to 100GB-200GB (25GB per layer)

in the future simply by adding more layers to

the discs.
