"Claims that moves to unify the two key competing HD video disc formats are progressing to a successful conclusion are "unfounded and erroneous", Toshiba said today. Toshiba is pushing HD DVD. Sony is promoting Blu-ray Disc (BD). Both formats use blue laser light to increase the capacity of a DVD-sized optical disc sufficiently to allow it to hold HD movie content. BD has the edge in capacity - 25GB per layer, to HD DVD's 15GB - but is harder to make and is potentially less resistant to damage. Both camps have won big-name backers from the movie, storage and computing markets."I dearly hope that both HD-DVD and Blu-ray will settle down for an unified format so that we won't have to see a reprise of VHS vs. Betamax format wars. ;)
