Humanity does not know if there is an intelligent life nearby the Earth and whether it exists at all, but we still continue to send messages to it. The main purpose of our messages is not to contact the aliens because even if they can find a plate it will be through tens of thousands of years. The main goal is to tell them or our future descendants about how we lived, what technologies we were using, what our planet looked like and about our interests. Of course, we will not be able to convey all these on usual plates or discs, that is why we need something more capacious. Fortunately, the scientists invented quartz disks. One such disk can record up to 360 tbs of information, and they can withstand temperatures up to 1000 degrees that is why it can store information for 14 million years without major damages. The main disadvantage of these disks is that the device for reading them is quite complicated and it will be difficult to explain to the aliens how to use them with one or two pictures. But I found a way out. I propose to combine the golden vinyl (phonograph) record that was sent by the Voyager and a quartz glass disk. We will send a gold phonograph record, a protective case, a soundbox(adapter) and a quartz glass disk. The chemical composition of the phonograph record, needle and case, as well as the scheme of use of the phonograph record will be the same as their analogs from the Voyager. Pictures that will be recorded on the phonograph record with explanations on how to collect the disc recorder. If one disk is not enough we can send few of them. It seems to me that this is the best way to send a message to the future.
