14 Cherri International / After Dark Digital, Security & Offset Printing celebrate 31 years of self employment on the Gold Coast, last April;. “Looking after Locals”. Compact Disc / DVD The first commercial compact disc was produced on 17 August 1982. DVD (an abbreviation of “digital versatile disc” or “digital video disc”) is a digital optical disc storage format invented and developed by Philips, Sony, Toshiba, and Panasonic in 1995. The world’s first DVD player was the Toshiba SD-3000, launched in November 1996. The first DVD players and discs were made available in November 1996 in Japan, March 1997 in the United States, 1998 in Europe and in 1999 in Australia. (12cm or 120mm International size). The Compact Disc and DVD although incredibly robust can be damaged by the oil from a human finger. After the surface is touched, an oxidization process begins, and generally within a year, the disc is discarded. DVD Drives are readily available with some laptop computers, AIO (All in One) and there are excellent portable drive to select from. The standard Compact Disc will hold 700 Megabytes and the DVD 4.7 Gigabytes (a standard Movie) of data respectively. There are two main classes of CD / DVD. ROM (Read Only Memory) and DVD R/W (Read & Write). (Blank Disc and Recorded on a Computer DVD Burner). “Burning” of your data, photos or video to a DVD is a safe, cheap and reliable storage medium. DVD Drives are available in various speeds. The original hardware speed was 2 x. Recording speed progressively increased over the years to 60x. Nearly all laptop computers have a 24 x DVD R/W (Reading & Writing) speed. Care must be taken if recording a DVD at a faster speed, as the slower DVD player may not recognise the disc. We recommend to record (burn) all DVDs at 8 x or 16 x, thus allowing compatibility with both a laptop and a desktop computer. Please call Mark on (07) 5537 8382 if unsure. Generally the software included with the DVD drive, such as Nero Express, is excellent, and will allow you to copy and produce most common disc types. Playing a modern DVD movie or music CD on very old equipment with limited RAM and Processor speed, may result in poor quality and interruptions. This is called “buffer underrun”. When choosing a CD or DVD, select by laser image. Turn the disc upside down, and then turn it into the light. A laser rainbow image will appear. The sharper the laser image, the higher the quality of the CD or DVD disc.
