In their day, magnabelts and dictabelts were stored flat in manila file folders kept in filing cabinets. As a result, these belts often creased on the ends where the belt had been flattened and occasionally grease pencil markings are found on them for identification.

Sonobands were often stored in their original boxes and housed one inside of the other. Consequently, the outer belts tended to stretch and the inner belts often curved in and out due to the weight of the other belts.

The most effective method of storage and preservation for belt mediums is in an acid free archival storage boxes wrapped around a piece of acid free cardboard. The cardboard will aid in the removal of creases or keep the belts from creasing. The boxes should then be stored in a temperature and humidity controlled storage area.
