Inside your CD player, there is a miniature laser beam (called a semiconductor diode laser) and a small photoelectric cell (an electronic light detector). The motor slows the disc down gradually as the laser/photocell scans from the center to the outside of the disc (as the track number increases, in other words).

How does a CD player read a disc?
The surface of the CD contains one long spiral track of data. The CD drive shines a laser at the surface of the CD and can detect the reflective areas and the bumps by the amount of laser light they reflect. The drive converts the reflections into 1s and 0s to read digital data from the disc.
How do you use a CD player?
Q: How do you use the CD player?
- Press the CD button.
- If you already have a disc loaded, it will automatically play from the point that you stopped it.
- If you don’t have a disc in, load it now.
- Just slide the disc into the player (with the label facing up).
- Use the Play/Pause button to play tracks or to pause a track.
Do CD players play all CDs?
Some CD players are designed to only playback commercially-produced CDs. Depending on the type of recordable CD media that you are using (such as CD-R or CD-RW discs), not all CD players will support the playback of the different types or recordable discs available.
Do CDs play from the inside out?
If you could stretch out into a straight line all the data stored on a single compact disc it would be over 4 miles long! ll Compact discs and other optical disc players read from the inside of the CD out, just the opposite of a vinyl record. full CD holds a maximum of 74 minutes of music.
How are DVDs better than CDs?
The CD and DVD are the optical recording medium where CD was devised as an audio storage format while DVD is used as the universal storage format. The latter technology DVD can hold data about 7 times more than CD and its format efficiency is also 32% greater than a CD.
What can you do with old CD players?
Below are 11 inventive projects you can try during your free time to reuse your old CD or DVD player.
- Add Bluetooth to an Old DVD Player.
- CD-ROM Into Vintage Speaker.
- Macro Lens From an Old Player.
- A USB Player From a DVD Player.
- DVD Player Becomes an Audio Amplifier.
- Arduino Mini Laser Engraver.
- Make a Burning Laser.
How do I play a CD on my laptop without CD drive?
One solution is to simply add an optical drive to the computer. Internal models were standard for many years, but compact computers like ultra slim laptops and all-in-one desktops just don’t have the space them these days. A better option is to use an external CD/DVD-writer that plugs into a USB socket on the computer.
Why won’t my CD player play certain CDs?
Unplug the power cord of the CD player from the AC outlet for 30 seconds. Turn on the CD player and attempt to play the disc. If the issue is still not resolved, remove the disc and unplug the power cord from the AC outlet. Let the CD player remain without power for 1 hour in case of condensation.
Why won’t my CD player play burned CDs?
Check and make sure you are burning as “Audio CD” format. Many older players cannot handle CDs burned in MP3 format regardless of type of disc they were burned to while newer car stereos should play CDs burned as MP3s. Additionally, many players cannot handle CD-RW discs.
Can old CD players play new CDs?
Many new CD and DVD players will play music CDs which were created using a data project, but most older players will not. Older CD players might not be able to play CD-RWs. Rewrite the CD as an audio project.
What direction do CDs read?
The dull side usually has a label on it telling you what’s on the CD; the shiny side is the important part. It’s shiny so that a laser beam can bounce off the disc and read the information stored on it.
Do CDs read from inside out or outside in?
It is faster to read from the outside of the disc than from the inside. At the same rotational velocity (e.g. 10000 rpm), the linear velocity on the outside of the disc is higher than the linear velocity on the inside of the disc, resulting in higher performance towards the outside.
