Understanding The Basics: How CDs Store Data
CDs, or compact discs, are optical storage media. They were first introduced in the 1980s and revolutionized the way we store and access information. Understanding how CDs store data is essential to comprehending the possibility of watching videos on them.
A CD consists of a polycarbonate layer, a metal layer, and a protective layer. The data is stored on the metal layer in the form of tiny pits and lands. These pits and lands represent the zeros and ones of binary code, which is the language that computers understand.
To read the data stored on a CD, a laser beam is directed onto the CD’s surface. When the laser hits the pits, it scatters; when it hits the lands, it reflects back. This difference in scattering and reflecting allows a device called a CD player or drive to interpret the pattern of zeros and ones and convert it into usable information, such as audio or video.
Videos stored on CDs are typically in a compressed format, such as MPEG-2. The CD player decodes the compressed video data and displays it on a screen. However, due to the limited storage capacity of CDs compared to DVDs or digital formats, the video quality on CDs may be lower, and the length of the videos that can be stored is also limited.
