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.

摘要

磁性视听 (AV) 媒体是文化遗产的重要组成部分。它包含声音、图像和其他数据等元素以供将来访问。霉菌生长会影响磁介质的劣化。随着时间的推移，霉菌会阻碍元素的恢复，甚至可能导致其完全丢失，从而导致我们文化遗产的流失。因此，需要对磁介质进行适当的维护以确保数据保留。本文介绍了一项国际在线调查的结果，以更好地了解有关受霉菌影响的磁性介质的当前知识。关于磁介质的信息有限，导致了这样的问题：文化遗产领域目前围绕磁介质模具有哪些经验和做法？该项目的目的是征求视听保护者和电影从业者对磁性介质（全涂层磁性胶片、磁性音频和录像带）、保护过程及其霉菌经验的意见。采用 Qualtrics 软件进行在线调查。调查表明，无论基材如何，磁性介质集合中都存在霉菌，但通过各种双重机械化学处理来抑制霉菌生长，霉菌可能仅限于不到四分之一的磁性介质。霉菌继续影响元件检索，因此霉菌处理是防止变质以确保数据保留的重要因素。保护过程以及他们对霉菌的经验。采用 Qualtrics 软件进行在线调查。调查表明，无论基材如何，磁性介质集合中都存在霉菌，但通过各种双重机械化学处理来抑制霉菌生长，霉菌可能仅限于不到四分之一的磁性介质。霉菌继续影响元件检索，因此霉菌处理是防止变质以确保数据保留的重要因素。保护过程以及他们对霉菌的经验。采用 Qualtrics 软件进行在线调查。调查表明，无论基材如何，磁性介质集合中都存在霉菌，但通过各种双重机械化学处理来抑制霉菌生长，霉菌可能仅限于不到四分之一的磁性介质。霉菌继续影响元件检索，因此霉菌处理是防止变质以确保数据保留的重要因素。
