Also, how much information can a blu ray disc hold?
A dual-layer disc can hold 50GB. To ensure thatthe Blu-ray Disc format is easily extendable(future-proof) it also includes support for multi-layerdiscs, which should allow the storage capacity to beincreased to 100GB-200GB (25GB per layer) in the future simply byadding more layers to the discs.
Beside above, what does blu ray disc mean? A Blu-ray disk (BD) is a high-capacityoptical disk medium developed for recording, rewriting andplaying back high definition video. It can storelarge amounts of data and was designed to supersede theDVD.
Accordingly, why does the Blu Ray player need the blue laser?
The name "Blu-ray" refers to the bluelaser (actually a violet laser) used to read thedisc, which allows information to be stored at a greaterdensity than is possible with the longer-wavelength redlaser used for DVDs.
What happens if you put a Blu Ray in a DVD player?
The reason that a Blu-ray Discplayer can play DVDs is that manufacturers decidedthat all Blu-ray Disc players included both blue andred lasers so that they could play both Blu-ray Discsand DVDs. When you place a DVD into aBlu-ray Disc player, it activates the redlaser assembly so that the DVD can be read.
