Why do program tapes and disks need to be stored safely and correctly away from contaminants and electromagnetic sources?

Program tapes and disks need to be stored safely and correctly to protect them from physical damage and data loss. Contaminants like dust, moisture, and chemicals can cause corrosion or degradation of the media, while electromagnetic sources can interfere with the magnetic fields that store data, leading to corruption. Proper storage conditions help ensure the longevity and reliability of the stored information, preserving its integrity for future access.
