Blu-Ray Disc

Blu-Ray Disc is the name of the new storage devices that looks like CD and DVD’s but it has more capacity in it.

Blu-Ray Disc was developed by BDA (Blu-ray disc association) and it finished in 2005. The BDA itself consist of many big companies that works together like Apple, Dell, LG, HP, and etc. They was working to made a new method of the storage devices. Before Blu-ray disc, we usually use CD’s or DVD’s that relying on red laser to read or write data. On blu-ray disc, they uses blue-violet lases instead, hence it’s name is blu-ray. The advantage of using a blue-violet laser (405nm) is that it has a shorter wavelength than a red laser (650nm), which makes it possible to focus the laser spot with even greater precision. This allows data to be packed more tightly and stored in less space, so it's possible to fit more data on the disc even though it's the same size as a CD/DVD. This together with the change of numerical aperture to 0.85 is what enables Blu-ray Discs to hold 25GB/50GB. Pioneer has recently pushed the storage capacity to 500GB on a single disc by using 20 layers.

Nokia 3G Booklet, Nokia’s first Net book

I know that nokia is one of the biggest company in cell phones, but i don’t know that Nokia want to compete in Net book and lately, Nokia introduce their first Net Book into the public at 2th of September 2009. Nokia has their own name for their Net book, that is “Booklet”. It has minimalist and elegant design like the one that Apple has for Macbook Unibody.

This Nokia Booklet have complete feature including the integrated OVI facility, wifi, 3G, AGPS and bluetooth. and for the operating system, it use the microsoft’s brand new product that is Windows 7. The most wonderful from this Booklet is the battery power, it used the 9 cell battery and can be used up to 12 hour.

The price is still to expensive, it’s about $ 799 or Rp. 8.000.000,- and I think that it must be a little bit cheaper because it’s competitor, Apple will release it’s new product in no time..
