No. The best you can do is use mathematics to compensate.
In essence represent the data as a set of equations and generate extra ones that will be useful in case you lose one. They have been doing this for decades in telecom/storage.

So the problem is analog vs digital nor the lack of mathematics in vinyl; it’s that ultimately any form of storage media requires a physical device and physical devices are bound to the problems of the physical world. This, by the way, is also why Amazon has multiple data centres in any given region. Why backups should always be stored off site, and why DR solutions are based in different physical premises.
