You did a great job explaining how they all work. I came here to know the difference between these 3 types but I didn't expected to find how they work so fascinating.
Thank you so much for your kind words! 😊 I'm really glad you found the explanation helpful and even fascinating! It's amazing how technology has evolved, and it's great to know you enjoyed learning about the differences and how they work. If you have any more questions or topics you'd like to explore, feel free to let me know. I appreciate your support!
Sound on a DVD disc is usually 48k for film tracks and sometimes 96k for music and that is stored as DTS or MLP for DVD-A. I don't think DTS do a 192k. Maybe 192kb/s, but most probably 448kb/s for Dolby.
While it's impossible for Sir Isaac Newton to explain physics personally, his groundbreaking work in the 17th century laid the foundation for modern physics. Newton's laws of motion and universal gravitation remain fundamental concepts in physics. To understand the differences in CD, DVD, and Blu-Ray technologies, we rely on the principles of optics, electromagnetic waves, and data storage, which are extensions of the laws of physics he pioneered. Today, experts in these fields build upon his legacy to explain and develop technologies like CDs, DVDs, and Blu-Rays. So, while Newton can't personally explain it, his contributions are integral to our understanding of the physical principles behind these technologies.
CD and DVD are just the medias themselves. -R is for writing data to them, and -RW is for rewriting data on them many times. It never was the most popular version of discs and is very uncommon nowadays.
DVD Re-Writable (DVD RW) discs are designed to store up to 4.7GB or 120 minutes of DVD-quality video. Unlike DVD-R's, you can add to or write over content on a DVD RW disc, making DVD Re-Writable discs ideal for backing up video and home movie collections.
CD-Rewriteable discs (CD-RWs) work in a similar CD-R Only, except that the change to the recording surface is reversable. Instead of dye or pits, these discs feature a layer of phase-change material. This material can exist in two different solid states: crystalline or amorphous. Most solids have a crystalline structure in which the atoms are close packed in a rigid and organized array. But some materials can have an amorphous state in which the atoms are organized not into arrays but randomly, as in a liquid. A common example of such a material is ordinary window glass, an amorphous form of silica.
They're both wrong. It's not the levels that encode the data, but the transitions between them. A transition encodes a 1 and no transition a 0. This does require that the data that actually goes onto the disc be encoded in a way that ensures a minimum and maximum number of zeroes between ones. CDs use a code that turns 8 bits of input data into 14 bits of output data, and it's that 14-bit form that actually goes onto the disc. Once a drive reads that, it puts it through the reverse 14-to-8 decoder, and then passes the results onto a couple of other codes to eventually arrive at the original data.

This was such a clearly distinguishable explanation of these 3 storage mediums, thanks for the upload
WE are so glad that this video helped you! Thank you.
I really needed these info! Thanks>
btw your setup, presentation, quality is kinda retrto and I like it.
Thank you!
Thanks for sharing this vedio so now I know what's the difference of each of it 😊
Very clear, thank you
Blu ray really needs a successor
maybe with the ps6...
when newton himself come down to explain us physics

Im confused because there are so many CD-R, CD, DVD, DVD-R, DVD-RW...

Hello;
I still don't know,how motion picture sound and color transfered to dvd disk,,,,,,,,,
i just wanted to know why dvd is rewritable,how does that work

wait, the other video says pit is 0 while flat surface is 1

Change from pits to lands (not pit) and vice versa consider as 1 , no change consider as 0.
Pits dont represent directly as 0 and lands as 1.🫡
