Do not interfile recordings of different sizes as smaller items may get lost or damaged, while larger items may be subjected to uneven pressure. Discs Remove shrink-wrap on LPs completely. Shrink-wrap can continue to shrink, thus warping the disc. Tapes Do not drop tapes. The shock could partially rearrange the ferromagnetic particles, effectively attenuating high frequencies.
Store tapes away from any sources of magnetic fields.
The plastic bag will trap moisture. Ten-inch reels should have supports in their boxes so that the hub bears the weight of the tapes rather than the flanges. Wind tapes slowly so that air pockets between layers do not form causing successive layers to be placed unevenly on top of each other. The unevenness will cause stress, expose binder to air and exposes edges to possible physical damage by the flanges. The tape tension might have to be readjusted to compensate for the removal of the heads.
