Answer 1

Hi SUSHANTA KUMAR M ,

HD DVD (Toshiba) vs Blu Ray (Sony).

The battle is over and Sony has won. Toshiba has announced they will discontinue production of HD DVD players.

The differences are (were) -

Both use interactive menus but differences are - Blu-Ray capacity is 50Gb and HD-DVD is 30Gb. HD-DVD is region free while Blu-Ray is divided into three regions. (Figures Sony will try to stick it to the consumer) A disadvantage to HD-DVD is they are not all hard coated as are the Blu-Ray. HD-DVDs scratch as easily as regular DVDs while the Blu-Ray are more scratch resistant.

Blu-ray, also known as Blu-ray Disc (BD), is the name of a next-generation optical disc format jointly developed by the Blu-ray Disc Association (BDA), a group of the world's leading consumer electronics, personal computer and media manufacturers (including Apple, Dell, Hitachi, HP, JVC, LG, Mitsubishi, Panasonic, Pioneer, Philips, Samsung, Sharp, Sony, TDK and Thomson). The format was developed to enable recording, rewriting and playback of high-definition video (HD), as well as storing large amounts of data. The format offers more than five times the storage capacity of traditional DVDs and can hold up to 25GB on a single-layer disc and 50GB on a dual-layer disc. This extra capacity combined with the use of advanced video and audio codecs will offer consumers an unprecedented HD experience.

HD DVD was designed by a consortium of companies (principally Toshiba and NEC) to be the successor to the standard DVD format, and is derived from the same underlying technologies. Since all variants except the 3x DVD employed a blue laser with a shorter wavelength, it can store about 3¼ times as much data per layer as its predecessor (maximum capacity: 15 GB per layer instead of 4.7 GB per layer).

Answer 3

They are just two different formats.

They aren't compatible, kind of like VHS and Beta back in the video tape days.

Answer 4

HD DVD is not more.

Answer 5

Sony has all ready incorporated blu ray technology.  They developed it.  Wal-Mart is supposedly supporting blu ray as are a number of other retailers.  Blu ray and HD DVD are high definition technologies.  The difference is that blu ray disc hold more information than hd discs.  Supposedly they are harder to scratch.  More companies support blu ray than HD DVD.  Paramount and Universal currently support HD DVD for now.

Answer 6

As said by the guy above me they are two different formats that arent compatible.

Sony, the pioneers in many electronic and optical storage technologies decided to go ahead with blu-ray. One of its rival companies (I dont know the name) continues with HD DVD.

May be Toshiba is in close ties with SONY so it is abandoning HD DVD Players

The biggest difference is in their storage capacities.

HD DVD can store about 20-25 GB on a single disc.

Blu-ray can store 25 on Single Layer & 50GB on Dual Layer

Hope that clears it all
