What is The Blue Ray Disc
What is Blu-ray?
Blu-ray, also known as Blu-ray Disc (BD) is the name of a next-generation optical disc format. The format was developed to enable recording, rewriting and playback of high-definition video (HD), as well as storing large amounts of data. The format offers more than five times the storage capacity of traditional DVDs and can hold up to 25GB on a single-layer disc and 50GB on a dual-layer disc.
Who developed Blu-ray?
The name Blu-ray is derived from the underlying technology, which utilizes a blue-violet laser to read and write data. The name is a combination of “Blue” (blue-violet laser) and “Ray” (optical ray). According to the Blu-ray Disc Association the spelling of “Blu-ray” is not a mistake, the character “e” was intentionally left out so the term could be registered as a trademark. The correct full name is Blu-ray Disc, not Blu-ray Disk (incorrect spelling)
The correct shortened name is Blu-ray, not Blu-Ray (incorrect capitalization) or Blue-ray (incorrect spelling) The correct abbreviation is BD, not BR or BRD (wrong abbreviation)
Blue Ray Disc Technology
Blu-ray, also known as Blu-ray Disc (BD), is the name of a next-generation optical disc format jointly developed by the Blu-ray Disc Association (BDA), a group of the world’s leading consumer electronics, personal computer and media manufacturers (including Apple, Dell, Hitachi, HP, JVC, LG, Mitsubishi, Panasonic, Pioneer, Philips, Samsung, Sharp, Sony, TDK and Thomson). The format was developed to enable recording, rewriting and playback of high-definition video (HD), as well as storing large amounts of data. The format offers more than five times the storage capacity of traditional DVDs and can hold up to 25GB on a single-layer disc and 50GB on a dual-layer disc. This extra capacity combined with the use of advanced video and audio codecs will offer consumers an unprecedented HD experience.
While current optical disc technologies such as DVD, DVD±R, DVD±RW, and DVD-RAM rely on a red laser to read and write data, the new format uses a blue-violet laser instead, hence the name Blu-ray. Despite the different type of lasers used, Blu-ray products can easily be made backwards compatible with CDs and DVDs through the use of a BD/DVD/CD compatible optical pickup unit. The benefit of using a blue-violet laser (405nm) is that it has a shorter wavelength than a red laser (650nm), which makes it possible to focus the laser spot with even greater precision. This allows data to be packed more tightly and stored in less space, so it’s possible to fit more data on the disc even though it’s the same size as a CD/DVD. This together with the change of numerical aperture to 0.85 is what enables Blu-ray Discs to hold 25GB/50GB.

‘Three Colours’ Trilogy $14.95 IllustratedThe Three Colours Trilogy by Krzysztof Kieslowski (1941-1996) is generally regarded as a major triumph of European cinema. An examination of how the ideals of the French Revolution-liberty, equality and fraternity-have meaning in modern life, the trilogy combines visual elegance, narrative complexity, and virtuoso performances to extraordinary effect. In this highly personal appreciation of the trilogy, Geoff Andrew analyzes how Kieslowski used his command of the cinema to open up the inner lives of his characters and to chart the way in which these lives are ruled by unseen forces. For Andrew, the trilogy is a poignant, thrilling hymn to the resilience of compassion in the face of adversity. Tracing the links between the trilogy and Kieslowski’s earlier work, he argues that Blue (1993), White, and Red (both 1994) are the summation of Kieslowski’s art. This book, which concludes with one of the last interviews Kieslowski ever gave, is a tribute to an exceptional filmmaker.Author Biography: Geoff Andrew is Film Editor of Time Out magazine and the author of several books, including The Film Handbook, The Films of Nicholas Ray, and Stranger than Paradise: Maverick Film-makers in the Recent American Cinema. |

Excerpt: Ex-Voto de 1662 is a painting by the French artist Philippe de Champaigne held in Paris’s Louvre . One of Champaigne’s most accomplished works, it is a votive offering (an ex-voto ) by the painter which depicts a miracle involving his daughter that is said to have occurred at the Port-Royal-des-Champs Cistercian convent .A ray of light illuminates Mother-Superior Agnès Arnauld , who experienced on the ninth day of her novena for Champaigne’s daughter, Sister Catherine de Sainte Suzanne, the hope that a cure would come for Sister Catherine. Catherine (seated, praying) was the painter’s only surviving child, and had been suffering from a paralyzing illness. Until that point, prayer and medical treatments (“potions, baths, unctions , and thirty bleedings”) had proven futile. After the Mother-Superior’s novena, Sister Catherine soon attempted to walk, and found herself increasingly mobile; the illness no longer seemed present. The painting is a statement of gratitude by the father for the cure of his daughter. The miracle it portrays also symbolized hope for the cause of the Jansenists , who were subject to persecution by ecclesiastical and civil authorities. The Jansenists followed Cornelius Jansen , who reasserted the theology of St. Augustine , and were in conflict with the Jesuits . Their refusal to sign a document condemning five propositions found in Jansen’s Augustinus resulted in their being deprived of the sacraments and confined to the abbey, which was eventually torn down.The |
