Toshiba have doubled the storage capacity of the single-layer HD DVD-R disc

Toshiba corp announced that they have developed a 30-gigabyte dual-layer HD DVD recordable disc, doubling the storage capacity of the single-layer HD DVD-R disc it developed earlier. They are saying a DVD-R disc can record data only once.

Sony corp is promoting a separate format called “Blue-Ray Disc”. It is very sad that these two corporations couldn’t agree on a common format :(

Well... this is a bit like C# and Java from Microsoft and Sun.
