Evolution of Computer Hardware #3 #2 #1 9 Facts about Optical Drive/Discs
Created by: Michael and Haris The first optical drive was created in 1958 when an inventor named David Paul Gregg who first got an idea and called it "VIDEODISK" as an optical disc drive. It was used as a 12-inch optical disc. An optical disc drive is a drive that retrieve or store data on optical discs. It holds more information than classic portable media which is a floppy disk drive. The type of optical drive depends on the type of optical disc it can accomodate. The optical drive has 3 different ones such as CD, DVD, and Blu-Ray player. What is an optical drive? How is it used and what happened back in the years? Let's find out. What is an optical disc drive? #4 #5 #6 #7 #8 Early 1960's 1958 - 1969 Thanks for watching our presentation 1958 2006-present The Blu-Ray have released in 2006 which is now commonly used today; it's the replacement of HD DVD's. It can store up to 50GB on dual layer and 25GB on single layer. It has the ability to play up to 1080i high definition quality. The first laser disk was demonstrated in 1972 and it was the Laservision 12-inch video disk. It was triple the size of a CD. It was developed by Philips, MCA, and Pioneer. In 1969, Philips had developed a video disc in reflective mode. 1972 A.K.A. Optical Disc The CD (compact disc) was introduced in 1976
by Sony and it was recorded only by
CD-ROM format. It's stored in 700mb memory; also it is just 4 inches. The laser
disc had ended here because the disc size was too big.
1976 1995 In 1987, Sony and Philips demonstrate the erasable, recordable and rewritable 5.25-inch optical drive which is now known as CD-RW or CD-R. Also, it is going to be released for DVD and Blu-Ray in later years. 1987 In 1995, the DVD (Digital Video Disc) was introduced and developed by Philips, Sony, Toshiba, and Panasonic. They can play in a video format which CD's cannot and it was the improved version of VCD's. It can store up to 8.7GB with dual layers and 4.6GB in single layer. HD DVD was later introduced in 2004. 1993 The VCD(Video Compact Disc) had been created in 1993 and it is capable of storing in a video format. They are dedicated to play in most DVD optical drives. It has the ability to store up to 800MBs. #9 The Future It is currently, the theoretical optical disc, Protein-coated disc (PCD) is being developed as an upgrade to the Holographic Versatile Disc (HVD). The HVD finished developing during mid-2008, and has a capacity of several terabytes, yet has the same size as a DVD/Blu-ray. 2008-present
