PPT-CD and DVD Drive 1 Compact Disc/Optical Storage Technology

It is the electronic recording storing and playing back of audio video or text in a digital form on a flat round plastic storage medium called a disc Its called optical because the information on the disk is read by a laser in a CDROM drive. It is an optical disc ma de of a special polycarbonate plastic known as Polymethyle Meta Acrylic The CD reading and writing uses Laser beam generating from the Laser diode of the CD drive Using the 780 nanometer near infrared Laser beam the data ca In the following fifteen years important progress has been made in optical discs DA conversion digital filtering digital signal processing magnetic tape hard disks and semiconductor processing power Research has made similar advances in identifying This optical disc digitally stores audio data in high quality stereo The CDDA specification was drawn up by NVPhilips and the Sony Corporation was summarized in the socalled RED BOOK All subsequent CD formats are based on this description The exten Presentation By: .
