- An optical drive is a device that reads and/or writes data onto a disc. To read/write data onto a disc, an ODD uses a laser diode to receive and send electromagnetic waves. Receiving these waves allows your computer to access what’s on the disc. Sending these waves enables the computer to write files onto the disc.

How do optical disks work? Optical disks rely on a red or blue laser to record and read data. Most of today's optical disks are flat, circular and 12 centimeters in diameter. Data is stored on the disk in the form of microscopic data pits and lands. The pits are etched into a reflective layer of recording material.

Right now, there are several types of optical drives available. Each one of these optical drives performs a similar set of functions. The way they perform these functions tends to vary. Before we dive into those functions, there are two types of optical drives to be aware of. The two types are internal ODDs and external ODDs. Just as the name sugge...
A standard optical drive gives you access to numerous possibilities. You can watch movies. You can listen to music. You can access the files on a burned CD or DVD. You can copy the contents of those discs onto your computer. You can back up important files to a CD or DVD. You can access those files years later. An optical drive that supports Blu-ra...
For quite some time, optical drives were considered a necessity. Just about every laptop and pre-built PCcame with one. Throughout the last ten years, though, things have shifted quite a bit. Fewer people purchase ODDs for their desktop PC builds, and fewer laptops come with a built-in optical drive. Some game consoles, such as the Xbox Series S an...
To answer this question, let’s return to our first question: what is an optical drive?It is a piece of computer hardware that can read and/or write various disc formats. So, if you own CDs and DVDs, you can use an ODD to access the contents of those discs. By doing so, you can watch DVD movies and shows, listen to your favorite music, install old v...

Jul 26, 2022 · On a desktop computer, the optical disk drive usually comes with a 12-volt DC motor. Meanwhile, the optical disk drives of laptops come with a smaller 5-volt DC motor. Thus, a desktop computer’s optical disk drive will consume more power than a laptop’s optical disk drive.
Aug 17, 2024 · An optical disc drive (ODD), also called optical drive in a computer allows you to use CDs, DVDs, and Blu-ray discs to listen to music or watch a movie. Most drives also allow you to write data to a disc, so you can create your own music CDs, video DVDs or even create of back-up copy of your important data files.
Jan 11, 2024 · The optical drive works by using a laser diode to read data stored on the optical disc in the form of tiny pits and bumps. The disc spins at different speeds according to its type, which is measured in RPM (rotations per minute).
