Blu-ray is an optical disc format designed to display high definition video and store large amounts of data.Blu-ray is the successor to DVD. The standard was developed collaboratively by Hitachi, LG that can focus more tightly than the red lasers used for writable DVD. As a consequence, a Blu-ray disc can store much more data in the same 12 centimeter space. Like the rewritable DVD formats, Blu-ray uses

Because Blu-ray utilizes a lens with a greater numerical aperture NA than HD-DVD, the laser spot can be focused with greater precision to fit more data on the same size disc. This allows Blu-ray to hold 25GB per layer 50GB on a dual-layer disc, whereas HD-DVD can only hold 15GB per layer 30GB on a dual-layer disc. Blu-ray has also adopted a higher data transfer rate for video and audio 54Mbps vs 36

Although both Blu-ray and HD-DVD are similar in many aspects, there are some important differences between them. The first is capacity. Because Blu-ray utilizes a lens with a greater numerical aperture NA than HD-DVD, the laser spot can be focused with greater precision to fit more data on the same size disc. This allows Blu-ray to hold 25GB per layer 50GB on a dual-layer disc, whereas HD-DVD can

The name Blu-ray Disc is derived from the blue laser violet coloured used to read and write this type of disc. Because of its shorter wavelength 405 nm, substantially more data can be stored on a Blu-ray Disc than on the DVD format, which uses a red 650 nm laser. A dual layer Blu-ray Disc can store 50 GB, almost six times the capacity of a double-dual layer DVD or more than 10 times if single-layer.Blu-ray

Blu-rayA high-capacity optical disc that holds 4.5 hours of high-definition video HD on a single-sided, single-layer 25GB disk. Announced in 2002 by Sony, Hitachi, Philips and other vendors, the Blu-ray technology uses a blue-violet laser that reads pits a third the size of a DVD on tracks that are packed much tighter together. Blu-ray supports the more advanced H.264 and VC-1 video encoding algorithms codecs

For Blu-ray disks, 1x speed is defined as 36 megabits per second Mbit/s, which is equal to 4.5 megabytes per second MB/s. However, as the minimum required data transfer rate for Blu-ray movie disks is 54 Mbit/s, the minimum writing speed for Blu-ray writers should be 2X 72 Mbit/s or 9 MB/s. The theoretical maximum speed for Blu-ray Discs is about 12&215; as the speed of rotation 10,000 rpm causes

CDs, so we could have full length, high quality digital movies on a single disc. Blu-Ray quality laser drives will likely be a similar successful break from BC. Announced in late 2003, Blu - Ray optical drives use a blue laser instead of traditional red DVD laser or infrared CD laser. Blue lasers produce light at shorter wave length than the others, so pits and lands can pack more densely. Blu - Ray

The name Blu-ray is nothing but blue-violet laser used to read and write blue ray disc. Because of its shorter wavelength (405 nm), substantially more data can be stored on a Blu-ray Disc than on the DVD format, which uses a red (650 nm) laser. A single layer Blu-ray Disc can store 25 gigabytes (GB), over five times the size of a single layer DVD at 4.7 GB. A dual layer Blu-ray Disc can store 50 GB
