Which is better CD or DVD?
CDs and DVDs are both common ways to store data, but there are some key differences between the two. In this article, we’ll take a look at what those differences are and which one might be better for you.
The first key difference between CDs and DVDs is that CDs are smaller and can hold up to 700MB of data, while DVDs can hold up to 4.7GB. This means that if you want to store a lot of data, a DVD is a better option.
Another difference between CDs and DVDs is that DVDs can store more than one type of data. CDs can only store data in a single format, while DVDs can store data in multiple formats, including video, audio, and pictures.
Finally, DVDs are more durable than CDs. This means that they are less likely to get scratched or damaged.
So, which is better CD or DVD? Ultimately, it depends on what you need it for. If you need to store a lot of data, a DVD is a better option. If you need a format that can store multiple types of data, a DVD is also a better option. If you need a format that is more durable, a DVD is again a better option.
How do I tell a CD from a DVD?
CDs and DVDs are digital audio and video storage media, respectively. They are both rectangular in shape, but CDs are typically smaller than DVDs. CDs have a diameter of 120 millimeters (mm) and a thickness of 1.2 mm, while DVDs have a diameter of 135 mm and a thickness of 1.8 mm.
CDs use a red laser to read data, while DVDs use a blue laser. The wavelength of the red laser is 650 nanometers (nm), while the wavelength of the blue laser is 405 nm. This is why CDs appear to be a different color than DVDs.
The pits and lands on a CD’s surface encode the data. A pit is a small, indented area, and a land is an area that is not indented. When a laser hits a pit, the light is reflected back and detected by a sensor. This reflects the binary code of “1” and when a land is hit, the light is not reflected and the code of “0” is detected.
DVDs use a higher intensity laser than CDs, so they can have more pits and lands per inch. This is why DVDs can store more data than CDs.
