Origins Of Blu-ray Discs

CDs, or Compact Discs, were the first optical storage discs used in the past until DVDs

, or Digital Versatile Disc, widely replaced CDs particularly because of its larger storage capacity. Today, the industry have yet again unveiled its new optical storage discs that surpasses the capabilities of DVD. This is the Blu-ray Disc. Blu-ray Disc (also known as Blu-ray or BD) is an optical disc storage medium designed to supersede the standard DVD format. Its main uses are for storing high-definition video, PlayStation 3 games, and other data, with up to 25 GB per single layered, and 50 GB per dual layered disc.

During the format war over high-definition optical discs, Blu-ray competed with the HD DVD format. Toshiba, the main company supporting HD DVD, ceded in February 2008, and the format war ended; in July 2009, According to Electronics Philippines enthusiasts, Toshiba announced plans to put out its own Blu-ray Disc device by the end of 2009.

From Then To Now

Sony started two projects applying the new diodes: UDO (Ultra Density Optical), and DVR Blue (together with Pioneer), a format of rewritable discs that would eventually become Blu-ray Disc (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. On February 19, 2002, the project was officially announced as Blu-ray, and Blu-ray Disc Founders was founded by the nine initial members.

The Blu-ray Disc physical specifications were completed in 2004. In January 2005, TDK announced that they had developed a hard coating polymer for Blu-ray Discs. According to Electronics Philippines enthusiasts, the BD-ROM specifications were finalized in early 2006. The first BD-ROM players were shipped in mid-June 2006, though HD DVD players beat them in the race to the market by a few months.

The first Blu-ray Disc titles were released on June 20, 2006. The earliest releases used MPEG-2 video compression, the same method used on standard DVDs. The first releases using the newer VC-1 and AVC codecs were introduced in September 2006. The first movies using (50 GB) dual-layer discs were introduced in October 2006. The first audio-only release was made in March 2008.

The first mass-market Blu-ray Disc rewritable drive for the PC was the BWU-100A, released by Sony on July 18, 2006. It recorded both single- and dual-layer BD-R as well as BD-RE discs and had a suggested retail price of US $699. As of June 2009, according to Electronics Philippines enthusiasts, more than 1000 Blu-ray disc titles are available in Australia, 2500 in Japan, 1500 in the United Kingdom, and 2500 in the United States and Canada.
