How to protect data from radiation and strong magnetic field?

AI Thread Summary
Strong magnetic fields can erase data on HDDs, making DVDs a more reliable option since they do not depend on magnetization. The impact of radiation on data retrieval varies based on the type of radiation involved. For enhanced data protection, consider using external backups in addition to DVDs. It's crucial to assess the specific risks of radiation and magnetic fields in your environment. Overall, transitioning to DVDs and implementing external backups is advisable for safeguarding data.

I keep my files using HDD, can my files still be retrieved under radiation and strong magnetic field?

Will it be better if I copy them into DVD disks?

Does anyone have any suggestions?
Thanks in advance for any suggestions

Strong magnetic fields at the disk can erase the data - DVDs are better, as they do not rely on magnetization.
Radiation: Probably depends on the type of radiation.

If you expect significant radiation or strong magnetic fields somewhere (why?), what about an external backup?
 

Thread 'Reflections at the source point of a transmission line'

I was using the Smith chart to determine the input impedance of a transmission line that has a reflection from the load. One can do this if one knows the characteristic impedance Zo, the degree of mismatch of the load ZL and the length of the transmission line in wavelengths. However, my question is: Consider the input impedance of a wave which appears back at the source after reflection from the load and has traveled for some fraction of a wavelength. The impedance of this wave as it...
