While the amount of storage a single layered Blu-ray disc will provide over the current DVD format is staggering, prepare to pick up your jaw off the floor. It appears in an attempt to jostle the competition, TDK has revealed plans of fabricating a monster 8 layer Blu-ray disc for commercial use.
While some will question the feasibility of such a huge disc, it is by far a huge technological milestone. The sky would very well become the limit with this disc. The days of having the hassle of using multiple DVDs back-up and restore whole hard drives would be eliminated and simplified to one disc, as the act of reformatting becomes a much more common practice to combat the effects of viruses, root kits, and spyware. The inclusion of TDK's new Durabris?coating, which seems to be nearly indestructible, should do a good job adressesing the concerns of the durability of such a high risk item.
Of course, there is also the factor of time. If it is going to take over 40 minutes to burn a dual-sided Blu-ray disc, then the estimate to burn a 200GB model would be roughly counted to be a minimum of 160 minutes. Also, the cost of such a "miracle of technology" would presumably be astronomically high, after all, a 200gb hard drive costs 200 USD normally. And finally, the more layers you add to a disc, the higher the chance of it "coasting" ( the disc failing to burn and becoming useless). It would be awful to spend so much on one of these, only to use it as a very expensive coaster for a coffee mug.
For TDK to make this a reality, they are going to have to address some of the concerns of consumers by making it affordable, durable, and burnable at a reasonable time with a very small chance of coasting. Otherwise, TDK might find their discs sitting in stores collecting dust.
=====================================================
前几年当你看到单层蓝光光盘的容量可以超过D9的时候...不要惊奇,因为今天TDK公司放出了他们要开发8层200G怪兽级商用蓝光光盘的计划!!!
这将是一个科技的里程碑,用户再也不用把他们的数据放入很多很多张的DVD刻录盘中,也不需要装入又大又笨重的硬盘中,只需要一张蓝光~
文章还指出蓝光的缺点:烧录时间太长以及昂贵! --- 一般的双层蓝光都要花费40分钟来刻满数据,而200G的蓝光则至少需要160分钟(近三小时)来刻满数据.而且想要享受这种怪兽级的科技,付出的钞票应该也是天文级数字  ,而现今200G的硬盘一般只要200美元左右.而光碟越多的"层"则表示有在刻录的时候应该会像走悬崖,万一出现刻录失败盘就报废了...而报废的代价也是很悲惨的..只见家里又多了一个很贵的咖啡杯垫 [s:83]
如果TDK真要开发这种有钱人的玩具的话,得注意减少光盘刻录失败的可能性以及增强耐用性,耐高温性以及给予蓝光一个能面向大众的价格...
要不然...他们会发现自己家的光盘正躺在商店的一个小角落吃灰尘  . |
