Storing records

  1. 1. Storing Records<br />By Cara Louise Venn<br />11U<br />
  2. 2. Different types of Records <br />Vinyl Record- is a record, an analog sound storage medium consisting of a flat disc with an inscribed, modulated spiral groove.<br />C.D.- stands for Compact Disc, it is an optical disc used to store digital data, originally developed for storing digital audio.<br />VHS- stands for Video Home System, it is a consumer-level video standard. <br />DVD- is an optical disc storage media format<br />Blu Ray- is an optical disc storage medium designed to supersede the DVD format.<br />
  3. 3. Vinyl Record<br />Gramophone records were the primary medium used for commercial music reproduction for most of the 20th century, replacing the phonograph cylinder, with which it had co-existed, by the 1920s. By the late 1980s, digital media had gained a larger market share, and the vinyl record left the mainstream in 1991.<br />The vinyl record regained popularity by 2008, with nearly 2.9 million units shipped that year, the most in any year since 1998. They are especially used by DJs and audiophiles for many types of music<br />
  4. 4. C.D<br />The Compact Disc is a spin-off of Laserdisc technology. Sony first publicly demonstrated an optical digital audio disc in September 1976. In September 1978 they demonstrated an optical digital audio disc with a 150 minute playing time<br />While some live CDs are designed to "demo" or "test drive" a particular operating system, there are live CDs made for many different uses.<br />installing a Linux distribution to a hard drive<br />testing new versions of software<br />testing hardware<br />system repair and restoration<br />high security/non-invasive environment for a guest<br />cracking/stealing passwords<br />network security testingbeing the primary or backup operating system for any computer<br />quick and simple clustering of computers<br />playing video games<br />internet banking;<br />And of course for music<br />
  5. 5. VHS<br />The Video Home System is a consumer-level video standard developed by Victor Company of Japan (JVC).The 1970s was a period when video recording became a major contributor to the television industry. Like many other technological innovations, each of several companies made an attempt to produce a television recording standard that the majority of the world would embrace. <br />Earlier in 1971, JVC engineers Yuma Shiraishi and Shizuo Takano lead the effort in developing the VHS tape format. JVC originally collaborated with Sony Corporation and Matsushita Electric (aka Panasonic) in building a home video standard for the Japanese consumer. Soon after, Sony and Matsushita broke away from the collaboration effort, in order to work on video recording formats of their own. Sony started working on Betamax, while Matsushita started working on VX.<br />
  6. 6. DVD<br />DVD is an optical disc storage media format, invented and developed by Philips, Sony, Toshiba, and Panasonic in 1995. DVDs offer higher storage capacity than compact discs while having the same dimensions.<br />Pre-recorded DVDs are mass-produced using molding machines that physically stamp data onto the DVD. Such discs are known as DVD-ROM, because data can only be read and not written nor erased. Blank recordable DVDs (DVD-R and DVD+R) can be recorded once using a DVD recorder and then function as a DVD-ROM. Rewritable DVD (DVD-RW, DVD+RW, and DVD-RAM) can be recorded and erased multiple times.<br />In 1993, two optical disc storage formats were being developed. One was the Multimedia Compact Disc (MMCD), backed by Philips and Sony, and the other was the Super Density (SD) disc, supported by Toshiba, Time Warner, Matsushita Electric, Hitachi, Mitsubishi Electric, Pioneer, Thomson, and JVC.<br />
  7. 7. Blu Ray <br />The first Blu-ray Disc prototypes were unveiled in October 2000, and the first prototype player was released in April 2003 in Japan. After that, it continued to be developed until its official release in June 2006.The name Blu-ray Disc refers to the blue laser used to read the disc, which allows information to be stored at a greater density than is possible with the longer-wavelength red laser used for DVDs.<br />Blu-ray Disc was developed by the Blu-ray Disc Association, a group representing makers of consumer electronics, computer hardware, and motion pictures. As of June 2009, more than 1,500 Blu-ray Disc titles were available in Australia and the United Kingdom, with 2,500 in the United States and Canada. In Japan, as of July 2010, more than 3,300 titles have been released.[3]During the high definition optical disc format war, Blu-ray Disc competed with the HD DVD format. Toshiba, the main company that supported HD DVD, conceded in February 2008, releasing their own Blu-ray Disc player in late 2009.<br />BluRay Discs may also come with a Digital Copy in which you can download the movie from the Digital Copy to a portable device capable of operating with a file in contrast to a DVD. Digital Copies may be used on iPods, iPhones, and iPads, as well as other tablet and smartphone devices.<br />
