    Dude it blows my mind how someone came up with this. Like ??? It’s so crazy that we can just put this tiny disc in this player (whatever form it is) and it clearly plays someone’s voice that was recorded at a different point in time. Like we can turn pictures and voices into 0s and 1s and idk but that’s pretty crazy if you ask me.

    Pits and lands equally reflect laser beam into sensor (it is called the law of reflection). Only at the transition from a pit to a land or land to a pit destructive interference occurs in the reflected laser leading to no or extremely dim beam enters the sensor. This destructive interference occurs because CDs are made so that the depth difference between a pit and a land is a quarter of wavelength of the laser used.

      Basically, there is a kind of dye instead of aluminium (if I remember correctly) and the laser has much more power when it's burning and not reading. So the heat forces the dye to change color at that particular spot and when the laser reads it, it reflects the laser less stronger.

      The lasers power burns the recorded layer why people say I’m going to burn songs onto a disc cause that’s exactly what’s happening when burning a disc the lasers power increases and the disc spins much faster the recorded layer on the disc changes colour you can see this if you only burn a small amount the burned layer appears darker then the blank recorded layer.

The player or burner will erase the data back to a blank free space then re burn new data. Over time it can weaken the recorded layer so it can’t be done over and over forever but who’s going to re burn the same disc 1000 times anyways

    • @ryans413
      @ryans413 2 ปีที่แล้ว

      Yes the table of contents are written in the middle of the disc the center next to the hole in the disc the laser read outwards until it hit the edge of the disc. Now on DVDs and Blu Rays you can have dual recorded layers meaning there’s two layers of recordable data on the disc. A DVD disc will read just the same as a CD but once the laser hits the edge of the disc it start going back inwards to the centre same with blu ray and now 4K blu ray discs have 4 layers of recordable data it’s just insane now lol

  • @JM64
    @JM64 3 ปีที่แล้ว +4

    So, correct me if I'm wrong but it goes something like this:
    The laser starts at the innermost part of the disc, and gradually moves outward in a spiral formation, with the CD player changing it's rotating velocity as the disc goes on.
    The laser reads data off of the disc via a binary code written with the bumps and recesses of a thin aluminum sheet.
    Assumedly you get more data onto a disc by increasing the concentration (data per area) of this spiral, which could be done by reducing the surface area each binary bump and recess takes up and making the laser more accurate as well as move outward slower.

    • @ryans413
      @ryans413 2 ปีที่แล้ว +4

      Correct this has already been achieved with DVD and Blu Ray DVD used a slightly slimmer laser so that meant it could read smaller bits and lands on the same size disc and blu ray took it a step farther with an even thinner laser wave length. Lets not forget dual layers and quad layers in the 4K blu ray discs multiple recordable layers to increase storage size. A typical Blu Ray disc is 50 gb and the disc is the same size as a CD disc that only holds 700 mb big difference there.

  • @jiffry58

    Why would the speed need to slow as the laser moves out? If the data is recorded at that speed it would be no different reading it. A record player doesn’t need to change speed

    • @AKIOTV
      @AKIOTV  6 ปีที่แล้ว +4

      That's true, but by slowing down the disc when getting to the outside we can keep the information density the same all the time. If the disc wouldn't slow down, these bumps would get further and further apart, meaning that a CD wouldn't be able to hold as much music. It would work, but it wouldn't be optimal.

If you think about it a single movie frame is made up of let’s say 8,000 pixels, if a 2 hour movie has 324,000 frames that means the disk has 2,592,000,000 total pixels stored on it, if the information for each pixel is written as a line of ten 1’s and 0’s that would mean the disk is holding a line of 25,920,000,000 characters of binary

    But if I delete all the contents of a CD and upload something else on it, how does the next CD reader know that the contents are changed? The grooves on the CD don’t change?

    That’s interesting 🧐 but my question 🙋‍♂️ that I have for cd 💿 player is that what happens if a song 🎵 🎧 🎶 is a half second or a full second like hanson this time around is 4:17 but sure about it on the cd 💿 on the back cover said 3:27 but my mom’s cd 💿 player said 3:26 and it’s a half second instead of a full second it should’ve been a full second instead of a half second and my mom’s cd 💿 player only has the runtime and the number and her cd 💿 player is old should she get a new cd 💿 player with cd 💿 text with song 🎵 🎧 🎶 titled like stereo world 🌍 and sure about it or not?

    but if the data is encoded into physical bumps, how is it possible to overwrite a cd with a computer?

      I agree with you. I think if light is reflected back into photodiode (sensor) then that is read as a 0 and if light is scattered (from the pit) then its read as a 1.

    I still only understand this as far as I understand vinyl, the 1s and 0s make enough sense, but I get how they can print tiny microchips with special printers to get crazy results in computers, how in the fuck is my cd burner from 25 years ago still able to crank out bootlegs like they where bought yesterday? Still a magic disc of metal to me
