I actually suggested this to a friend when we were in highschool as an idea for a physics demo, this was back in 2002, it's interesting seeing other people do the same thing, he started with a torch and a solar panel, if I recall correctly that was his idea, I then suggested using a red laser and the sound clarity was much better due to the focused beam. He just used a microphone to transmit his voice though

That's not gonna work. The idea of storing data is that the semiconductors in the electronics are locked in such a way such that it will always be 0 or 1. This locking mechanism is using a circuit known as a latch. In the past, storing data uses a capacitor, where a full capacitor means 1 and empty capacitor is 0. However, capacitor charges depletes over time. Therefore, every hour or so the capacitors (which contains 1) will need to be recharged. In terms of HDD, they used magnetic field to induce magnetism to a small metal pixel on a metal plate. Then to read the data, a magnetic field sensor is dragged across the metal to read the 0 and 1. As magnetism also disappears over time, it is also required to be recharged, but not as frequently as capacitor, maybe every month or so. This is why SSD is superior to HDD, as SSD uses the latch system, that does not require recharge. With your idea about light, it would be very expensive to keep a light on indefinitely just to keep a data. Even if we're using luminescent paint to store the data for example, we know that luminescent paint even dims out over time. Therefore you would need to "recharge" it by giving it light again.

How can I use a laser pointer that uses a button to turn on/off and not the pen clip like what you used? I have a similar experiment to this, but would love to try using a laser instead. Thanks for the help!
