The advent of Blu-ray technology has led to the introduction of high capacity storage discs to meet the demand cause by the rapid growth of high definition television (HDTV).<br><br>Blu-ray discs get their name from blue laser technology. The shorter wavelength of the laser is the reason it is blue in colour. The blue laser has a wavelength of 405nm compared with the wavelength of 650nm for DVD which utilises red laser technology. The benefit of having a blue laser with a shorter wavelength means it is possible to write smaller data pits and therefore vastly increase the amount of data on the disc.<br><br>Blu-ray discs offer 3 to 5 times the storage capacity of a standard recordable DVD disc, enabling the recording, rewriting and playback of high definition video (HD).
Excellent price, easy to order on the website, quick delivery (paid as I needed it quickly but if I hadn’t it was free), well packaged, bought as a gift and recipient very happy
I 'needed' a new phone and A1 Tech offered my choice at a very good price. Buying on-line was straightforward. Communication was excellent and the phone arrived exactly as promised. I also bought a charger which came a couple of days later, but that was fine.
First time heard and ordered from this company and have to say everything went as good as it could
The item was cheaper on here than anywhere else at the time
They kept me informed about the delivery and it arrived when they said
Great service, quick delivery and exactly as described. Not used the phone yet as, being brand new and a gift for my wife, it's not yet been used, but it looks great.
Fantastic company, prices are always great and very competitive. Ordered a few things now and delivery is always really quick. Kept up to date with order tracking and packaged well and safely. Products are exactly what they say they are.
