ABSTRACT
Magnetic audiovisual (AV) media makes up a significant part of cultural heritage. It contains elements such as sounds, images, and other data for future access. Mould growth can impact magnetic media deterioration. Over time, mould impedes element retrieval and can even cause its total loss, resulting in the loss of our cultural heritage. Therefore, proper maintenance of magnetic media is required to ensure data retention. This paper presents the findings of an international online survey to better understand current knowledge surrounding mould-affected magnetic media. Information on magnetic media is limited, resulting in the question: what are the current experiences and practices surrounding mould on magnetic media in the cultural heritage sector? The aim of the project was to seek audiovisual conservators and film practitioners’ opinions about magnetic media (full coat magnetic film, magnetic audio, and video tapes), conservation processes, and their experience with mould. An on-line survey using Qualtrics software was employed. The survey indicated that mould is present in magnetic media collections regardless of substrate but may be limited to less than a quarter of magnetic media with various dual mechanical–chemical treatments used to combat mould growth. Mould continues to impact element retrieval and thus mould treatment is an important factor in deterioration prevention to ensure data retention.
