But I don´t trust in longevity of BD, I think it´s designed to be unreadable after some years to make sure that consumers buy the next generation and so on …
Important photos I would store on different storage-media and would copy to the next one after some years.

But I´m not sure that normal degrade is comparable with the simulated which let us think it last 1000 years.
And even when, would a drive still works in 20 years? Enough components in the drive would age even if not used
