Blu-ray, cunoscut si ca Blu-ray Disc (BD) este numele noului disc optic ce va permite redarea televiziunii de inalta definitie HDTV (high-definition television).
Blu-ray va permite inregistrarea a peste 2 ore in format HDTV sau a peste 13 ore in format SDTV (standard definition television) pe un singur disc a carui capacitate va fi de 23.3GB, 25GB sau 27GB (single layer) sau 46.6GB, 50GB sau 54GB (dual layer).
Blu-ray foloseste o raza laser albastra, a carui lungime de unda este de 405 nm, fata de 650 nm (raza laser rosie) cat are in momentul de fata standardul DVD.
Player-ele/Recorder-ele Blu-ray vor fi compatibile cu standardul CD/DVD, ele putand citi CD-uri si DVD-uri.
data de lansare: 2005-2006

HD-DVD este similar cu Blu-ray, utilizand aceeasi raza laser albastra pentru a stoca capacitati mari.

Daca Sony transformase DVD-ul in SACD, oare sunt ei atat de nebuni in cat sa o faca din nou cu noul format?  :sd:

sony a luat doua tepe cu vhs beta tape si cu mini-discul (le-au facut format proprietary, si nu a prea prins la public). nu au repetat greseala cu memory stick, si asta merge destul de bine.
pana la blue ray, deocamdata a aparut dual layer dvd-rw (inca scump, ne-practic, ma refer la media), tot cu sony varf de lance la dvd dl burner.
