Jabarkan Asal dari Cakram Blu-ray dalam bahasa sunda

Sony started two projects applying the new diodes: UDO (Ultra Density Optical) and DVR Blue (together with Pioneer), a format of rewritable discs which would eventually become Blu-ray (more specifically, BD-RE). The core technologies of the formats are essentially similar.

The first DVR Blue prototypes were unveiled at the CEATEC exhibition in October 2000. Because the Blu-ray Disc standard places the data recording layer close to the surface of the disc, éarly discs were susceptible to contamination and scratches and had to be enclosed in plastic cartridges for protection. In February 2002, the project was officially announced as Blu-ray, and the Blu-ray Disc Association was founded by the nine initial members.

The first consumer devices were in stores on April 10, 2001. This device was the Sony BDZ-S77; a BD-RE recorder that was only made available in Japan. The recommended price was US$3800. However, there was no standard for pre-recorded vidéo (BD-ROM) and no movies were reléased for this player. The Blu-ray  standard was still yéars away, since a new and secure DRM system was needed before Hollywood studios would accept it. Nobody wanted to repéat the failure of the Content Scramble System for DVDs.
