In the era of cloud storage and digital downloads, it’s easy to forget the humble beginnings of data storage. One of the most significant innovations in this field was the introduction of CD-ROM, or Compact Disc-Read Only Memory. Although CD-ROMs may seem outdated compared to modern storage solutions, their impact on the technology landscape was profound. In this article, we’ll delve into the function of CD-ROM and explore its history, capabilities, and contributions to the world of data storage.
What is CD-ROM?
CD-ROM is a type of optical disc that stores digital data in the form of pits and lands, which are arranged in a spiral track on the surface of the disc. The data is stored in a read-only format, meaning that once the information is written to the disc, it cannot be altered or deleted. This makes CD-ROM an ideal medium for distributing software, games, and multimedia content.
The CD-ROM format was first introduced in the 1980s, building upon the technology of audio compact discs (CDs). The first CD-ROM discs had a storage capacity of 650 megabytes, which was a significant improvement over the floppy disks and cassette tapes used at the time. Over the years, the storage capacity of CD-ROMs increased, with some later versions capable of storing up to 800 megabytes.
How Does CD-ROM Work?
The CD-ROM works by using a laser to read the data stored on the disc. Here’s a simplified explanation of the process:
- The CD-ROM drive inside a computer sends a laser beam to the disc, which is spinning at high speed.
- The laser beam reflects off the disc and is detected by a sensor.
- The sensor interprets the reflected light as a series of 1s and 0s, which represent the digital data stored on the disc.
- The CD-ROM drive sends the data to the computer’s processor, which interprets the information and executes the appropriate commands.
